Comment Re:I'm Confused on the Article's "Cathedral" (Score 1) 200

News to me too, but according to that same article, they were more in that direction (but moved in the bazaar direction in response to CatB). Closed-source, meanwhile, is the obvious next step from "source is unavailable except when the cabal releases" to "source is unavailable, full stop"; the original definition of "cathedral" does represent that, if only by presenting a weaker form of it.

You say "millions of ... daily hits". For simplicity, let's say that you get about 1 million hits per day; that's about 10 hits per second, and that's if they're spread out evenly throughout the day. If it's fairly business-centric and USA-centric, then let's say that you get about 90% of those hits during a period of about 10 hours; that's more like 25 hits per second. Now how long will it take your server, on average, to process one hit (taking multiple processes/threads/etc. into account)? The difference between 0.02 seconds and 0.12 seconds now determines whether it gets swamped or not.

If you do run this type of volume on your own kit, then you'll need to pay serious attention to (1) optimizing for processing speed (including volume of data sent back and forth between your site and the user) and (2) using multiple web servers and/or database servers with load balancing.

Just this past weekend, I moved some stuff off an old Windows 98 workstation at a client. I'm pretty sure the user hadn't been performing percussive maintenance... Also upgraded the primary application software (for the first time since 2005 or so) and a few custom reports (dating back to the pre-Crystal Reports era).
