Allow me to summarize a reply.

As for the modpack, these days I mainly use the direwolf20 pack from FTB launcher. I think it's only just over 100 mods.
I also used to play the TolkenCraft pack (no idea how many mods it used)

As for my world age, it was generated this year so ~6 months old. I couldn't tell you play time, but I'm not really near the god-tier you describe. I do have a small-to-medium AE setup if that counts :P

Also upon generating a new world I see similar results, although in that case the client is being pretty busy generating the new world, so I'm not sure if that counts.
But how long should initial world gen take? Shouldn't the lag be mostly gone in 10-15 minutes?
Yes it certainly has less lag after those 10 minutes, but it is still pretty bad as previously described.

Back in the 1.2.5 days and Tekkit, I recall seeing insane FPS rates in the f3 debug screen. Like on the scale of 400 (I'm pretty sure that was on my gtx275 but I don't remember)
Granted plenty of other problems back then, but still...

Now for the bits that stand out above the rest from your post:

First, thank you for the link.

Second, NO, of course I don't have any Java clues, I'm no Java developer. Why would you even assume I would?
I only use Java because another program I desire to run needs it.

I can't really be expected to customize my Java settings when no one has said that is needed.
So I naturally left everything default.
And yes, it is 64 bit Java JRE

Yea thanks for suggesting I'm spreading FUD.
Let me guess: "Can not reproduce, didn't try or listen to explanation. Closing ticket as NOFIX"

Seriously.. I was/am sitting here offering to run any and whatever actual tests, benchmarks, debugging, and anything else I could do to show the results of these problems to your own levels of expectation... so clearly FUD is a worth mentioning option.

I already and once again grant I could be doing something wrong.
So what the fuck do I do to do it right?!

A fresh install of FTB, fresh download of modpack, on an updated Java with default settings...
On a 6-7 month old Win7 Pro install.

I did run IE once to download Steam and a package from microsoft. All minecraft related files came from my main PC (although all came directly from Oracle, Mojang, and FTB)
In-client downloads, windows updates, and a MS security essentials DL from microsoft, are the only other internet usage that PC sees. No other web browsing is done from there.
(As nice as MSSE is on system resources, I can't say I trust it completely)

But despite all that, and not that I'm trying to force you to help me, but if there is nothing that will convince you of what I'm saying (as seems to be the case) then you have no justification for calling me a liar.

Sorry for the double-reply, but after answering your direct complain I forgot to put in my on-topic reply.

Using Minecraft for education is a completely valid option to be considered.

I know from experience it can do so quite well in some cases, being both on the instructor and student side of things within minecraft.

I was an instructor teaching Lua programming using ComputerCraft on a server setup specifically for education.

I was also a student in various vanilla redstone classes, as my redstone skills are quite lacking compared to even a moderately advanced builder.

Some of the articles listed classes sound like they would work great within minecraft especially creative design, physics, and math, but even advanced math like logic and branching out into either programming or electronic/logic design is a wonderful fit.

I admit to being curious and confused on the history lessons being better in Minecraft, but if someone with more teaching skills than I have wishes to give it a try at making it work, more power to them!

I'm sorry you are having clock malfunctions, but just so you know the current year is 2015 :P

But seriously, when modded minecraft takes 6+ gigs of ram to load in 15 minutes, and after that gives you mainly 1 frame every 3 seconds lasting up to a half a minute, with spurts of 10 frames a second for a couple seconds, it's really hard to give good words to any of the components involved.

But OK, modded minecraft isn't fair. So how about vanella minecraft?

The stock 1.7.10 client under Java 7 (the last cross-platform version), or even the stock 1.8 client under Java 8 (with lwjgl 2.0, which is windows only for now) - I get between 20 and 25 frames a second with the occasional one second lock up every few minutes.

This is on an i7-5820k and Nvidia GTX 970 with 32GB ram - a PC that ranks 97% world wide in 3dmark.

Again, it is extremely difficult to give any good words to any component involved here.

The joke used to be "Can it run Crysis?", but since the answer is now "Yes, at 120fps on a 4k display" the joke has become "But can it run modded minecraft?"

Note I am refraining from putting any blame squarely on any single component involved here, including Java.
(My only real Java-ish related complaint is the sorry state of lwjgl 2.0, but even that isn't a Java problem specifically and so shouldn't count)

If you would like me to run any specific benchmarks on my PC to give the supporting numbers, please feel free to ask. Just let me know what and how and I'll post up the results.
For a baseline, I do own 3dmark, as well as some current high end games like Crysis, Shadow of Mordor, and GTAV which I can benchmark side by side.
What I sadly do not have is any form of screen capture software, nor the experience with such software to produce a video.

You know whats worse than todays pilots flying ancient airplanes, a brand new extravegantly expensive F-35 that cant match an F-16 or F-15E built in the 80s, planes built for a fraction of the price.

The F-35 might be an OK successor to the F-117 as a mostly stealth small bomber, but all indications are its completely worthless in a close in dogfight, you just have to read the leaked report from a recent test against an ancient F-16.

The F-35 simply doesnt have enough power, cant turn fast enough and bleeds off to much energy. The pilot found one manuever he could use to shake the F-16 but it consumed so much energy he had to run away and try to get the energy back.

The F-35 will also be horrible in the close air support role at which the A-10 excels, again at an even smaller fraction of the price tag.

F-35 is a classic jack of all trades and master of none.

There might have been a place for a few hundred of them but for the U.S. and every allied air force to think they are going to use one horrible design to replace every fighter they have is complete insanity. If it ever reaches full deployment, one accident or problem and the entire western world will have no air force. At least the Navy has the sense to keep the F-18 alive.

The F-35 is a tribute to the extent Lockheed has seized total control of Congress and the Pentagon, they could literally sell the Air Force actual turkeys for a hundred million a pop and get away with it.

Those B-52â(TM)s still flying today is because Northrop, has also seized control of the Air Forces generals made the B-2 so expensive and so few in number the Air Force canâ(TM)t afford to risk it in combat.

Besides the U.S. has been fighting people living in mud huts who have no air force and air defenses for over a decade, B-52â(TM)s and A-10â(TM)s work incredibly well in that role.

It could be worse. I'm eating steak off of a screwdriver :{

That depends which definition of trust you mean.

Do I trust them to respond in a certain way under a given set of circumstances?
Yes, I believe I can predict exactly how they will abuse and eventually clusterfuck OpenDNS, and I predict it will not be pretty.

But do I trust them to have my best interests at heart?
Hell no.

Who in hell cares, if they are taking them off my hands at no cost to me?

that Bing maps is a failure, how will Microsoft compete against Google in the search business without maps? Will they integrate Google Maps results to Bing?

Another question which is at least as glaring: what would be the reason to keep running Bing at all WITH NO MORE ADVERTISING REVENUE?

Then explain why there's a court involved, and why the government will enforce collection of the civil suit damages?

Because the alternative would be some kind of wild west scenario where the party who can summon the most naked force to his cause wins. That might be the wet dream of anarchists, but most civilized societies have a consensus that this is a better way.

You're also assuming that your ISP would allow you to do such a thing, and not brand you as someone up to no good, and cut you off.

I pay my ISP to give me a pipe to the internet. I use that pipe to contact numerous different public servers using numerous different protocols. If some of those servers are DNS servers, and I use DNS protocol to contact them, it is none of their mother fucking business. And indeed, my ISP clearly couldn't care less if I am doing it. If they tried to stop me, I would just ssh tunnel forward through a VPS and fuck em.

I never heard of anybody ever being "cut off" for doing this.

Well if IPv6 packets can pass at all, clearly they support IPv6.

The problem is that they likely are accidentally supporting it with no knowledge about doing so.

Would you put your Windows box on the IPv4 Internet with no firewall what so ever?
I don't mean having a firewall and accidentally misconfiguration it, I mean having a firewall and not adding a single rule.

Well, that's exactly what these VPN providers did for the IPv6 protocol. They have zero IPv6 firewall rules.

So while inbound IPv4 packets are filtered with a default deny rule and any allow rules the customer wants, also likely filtering some outbound as well, their IPv6 rules are default allow.

Odds are if you fired up a PC with IPX or NetBEUI as the protocol, their firewall would gladly allow that traffic unfiltered as well.

For example in the Linux iptables packet filter, you can disable the IPv6 protocol completely with a single command:
iptables -I INPUT -p 41 -j DROP

If course using IPv6 properly is a bit more work, as you have to allow the ipv6 protocol in the main iptables, and use ip6tables or something like that for filter rules on the other IP stack.

Either way, allowing everything (no matter what protocol) has always been said to be unwise, and now these companies and their customers can see why.

For what it's worth, it was exactly that which drove me away from yahoo search and onto google search back in 98-99.

And I never did mind that yahoo search had links at the top to yahoo maps and yahoo games and such, nor do I mind google doing the same.

It was actually the 20+ ads on the main yahoo page (top, left, right, and center) that drove the last nail in. At least on that one aspect, google continues to win by a landslide to this day.

Yes it was mildly annoying when google changed their sponsored ads from having a nice different color background from the search results, but even now there is still a nice and noticeable yellow "Ad" icon next to those results that serves the same purpose.

It sounds like your opinion on where the threshold for abuse falls differs from mine, but for me personally google still hasn't crossed it.
It's just surprising and saddening that no one else seems to believe me regarding my opinion, saying I must be wrong or worse a stupid idiot for making an informed conscious choice in the matter...

Have you ever had a LEGO brick turn squishy on you? Because that's what they're made of, ABS plastic.

It's a plenty tough enough material that I used it to manufacture parts for a geodesic dome for outdoor use as a greenhouse, and it held up fine. I also manufactured gears for a friends high end RC car after the manufacturer had gone out of business. Those gears see a lot of stress, and they held up fine.

ABS is a great material, and so is PLA.

The only part I've found complex is finding out where and how various apps actually store their data, particularly when I don't really have much interest in the app.

Apart from that however, system restoration is pretty trivial.

For example, let's say a basic Apache webserver.
Apache stores it's master website in /var/www and personal websites under a users homedir.

So you have a pre-backup script (or just a cronjob) that runs:
dpkg --get-selections >/root/current-packages.txt

Backups should always consist of /root , /home , and /etc no matter what.
As mentioned with Apache, we need to add /var/www to that mix.

Now to do a restore, you install from the debian disc, then restore your directories from backup.
Then run:
apt-get update && dpkg --set-selections /root/current-packages.txt && apt-get install

At that point all your software and dependencies are back from the listing in /root , and services started up from your own configs in /etc , and in this case Apache is happily again serving from /var/www and homedirs.

That's it. One CD boot, one reboot into the live OS, and a few commands to restore all data/software/apps/libraries/dependencies which get started after install and run from your edited configs just as before.

Again, the only real trick is not missing any application data. Especially from a sysadmin point of view.
A user of the machine asks for WierdSQL. What do I care about learning a new SQL server? I just want to make sure I can make consistent and regular backups of its data.
I don't want to hear someone say "Oh the raw DBs are in /var/blah/blah" which are always in use and always changing.
I want to hear "Use this command to backup the data to date/time stamped .bak files where ever, then go backup that whereever dir - and here are the commands to restore .bak files into a fresh install"

For servers I setup for myself, it's pretty guaranteed I either know the software already and can answer all of the above questions, or I'm just learning it and so there is no risk or useful data to be lost and it doesn't matter.
But for servers I run for others, yes it can be a lot more work to learn those things, and is certainly not nearly as fun as the former.
