I should add that ZFS uses more CPU.

I did a quick test with 2 identical VMs on my desktop with Intel SSD, I installed the ubuntu-zfs as from the article and I installed btrfs-tools.

The VMs have 4 CPUs and 4GB of memory, 3 virtual disks.

The btrfs has RAID1 data and meta data, the ZFS setup used RAIDZ as in the article:

mkfs.btrfs -m raid1 -d raid1 /dev/vdb1 /dev/vdc1

(I needed to create the partitions, for some reason the ZFS version didn't want to work without it)

My quick stupid test, create a large file:

ZFS:
500+0 records in
500+0 records out
524288000 bytes (524 MB) copied, 16.8489 s, 31.1 MB/s

real 0m16.853s
user 0m0.000s
sys 0m0.480s

btrfs:
500+0 records in
500+0 records out
524288000 bytes (524 MB) copied, 15.232 s, 34.4 MB/s

real 0m15.234s
user 0m0.000s
sys 0m0.640s

Actually, i tried that, it give me an error.

Sun doesn't exist anymore, it's all Oracle now.

Interresting enough btrfs works really well on a phone.

I do know kFreeBSD atleast supports ZFS, pf, pfsync and carp from OpenBSD which are all part of FreeBSD kernel.

Not sure about DTrace, haven't tried that.

Actually you can't turn it off, because Opera Mini isn't a real browser, that is the whole point of Opera Mini. It is just a client which displays what the Opera server prerendered.

The question was: why not Linux for security.

You answer is: MS skills ?

I know businesses don't really care about security, but still finding a good admin with MS skills has to be atleast as hard as finding a Linux admin.

Actually, the fairly populair Spotify uses P2P protocols to distrubute (part of) the content to users as well.

So, ironically, if you block P2P protocols you'll more than double the price of Spotify and people will stop using it even though Spotify is one of a few working solutions of the music industry.

Do you really believe that Linus would use GPLv3 for the kernel ? You most be kidding. Linus is very clear about why he does not want GPLv3. He is happy with GPLv2.
