>why is Apache still spawning processes for every request that comes in... don't they realize the overhead of that??

I'm not sure if you're serious about that or not, however

  • Since Apache2 you could change multiprocessing modules. The prefork MPM does the equivalent of apache1 and makes a number of forked off worker processes.
  • Apache1/Apache2-prefork don't use one process per request unless you specifically request it to. Worker processes are retired after a number of requests (usually a couple hundred) as this helps to contain the impact of any memory leakage that may have been accidentally introduced etc
  • Apache1/Apache2-prefork doesn't wait for a request to spawn the new worker processes, It spawns them in the background and hands incoming requests over to them. An incoming request doesn't have to wait for a worker process to spawn
  • Though you can argue that windows is reasonably performant in general, one primitive that linux that's far faster is process creation. Processes are meant to be cheap in unix systems, and used as such.
  • Separating things out into multiple processes helps to contain the effect of any bugs. Worker processes can crash all they want and won't impact the service as a whole.

I tend to use prefork MPM on servers for the isolation, unless I'm expecting a tonne of traffic, but by all means use the worker MPM, which uses a large amount of threads inside a single process.

Microsoft Vista, IE7 Banned By U.S. DOT 410

An anonymous reader writes "According to a memo being reported on by Information week, the US Department of Transportation has issued a moratorium on upgrading Microsoft products. Concerns over costs and compatability issues has lead the federal agency to prevent upgrades from XP to Vista, as well as to stop users from moving to IE 7 and Office 2007. As the article says, 'In a memo to his staff, DOT chief information officer Daniel Mintz says he has placed "an indefinite moratorium" on the upgrades as "there appears to be no compelling technical or business case for upgrading to these new Microsoft software products. Furthermore, there appears to be specific reasons not to upgrade."'"
