Apache configuration question
Good morning, all. I'm passing this on from a co-worker who's having a headache. If you need any additional info to answer this please ask. Anyway... Apache (1.3.23) by default appears to run single threaded. This apparently can be changed at compile time, but we're having trouble finding how. Any info?

RE: Apache configuration question
Thanks to Kurth Ben for the info so far. I'm passing that on to my chum working the Apache issue. We are running on Unix (Sun for this particular box) and I believe we are considering v2, but we're stuck w/ 1.3.23 for now. Any more info is appreciated greatly. -Lawrence -Original Message- From: Benjamin Scott [mailto:[EMAIL PROTECTED]] Sent: Monday, April 29, 2002 9:40 AM To: Greater NH Linux Users' Group Subject: Re: Apache configuration question On Mon, 29 Apr 2002, at 9:31am, [EMAIL PROTECTED] wrote: Apache (1.3.23) by default appears to run single threaded.

There is some info on threading (HAVE_PTHREAD_SERIALIZED_ACCEPT) in the performance tuning notes at http://httpd.apache.org/docs/misc/perf-tuning.html.

Well, it looks like Ken nailed our pretty well.

It's not that it can be configured at compile time, per se. However, there are hacks to the http_main.c that can be done to make it threaded, and there are some third party patches that will do it for you. I'm not an expert on the subject (like Ken is ;-), but according to the performance tuning docs, it can be done. However, I'm also seeing that multi-threaded has worse performance than single-threaded. C-Ya, Kenny -- Tact is just *not* saying true stuff -- Cordelia Chase Kenneth E.

I am getting the impression that you are operating under the assumption that you need multi-threaded operation for some reason. Is that impression correct? Because the assumption may not be. Apache does quite well as a single-threaded, multi-process server. Is there a reason you want threading? -- Ben Scott [EMAIL PROTECTED] | The opinions expressed in this message are those of the author and do not | | necessarily represent the views or policy of any other person, entity or | | organization.

RE: Apache configuration question
Actually, there is...but my explanation would probably not be very clear (not to mention probably embarrassing). I deal with this mostly from the point of view of the WebSphere Application Servers and head up the performance monitoring drive. I'll ask my partner-in-crime who's running w/ the Apache issue to write me up a little note about the problem and I'll pass it on. -Lawrence -Original Message- From: Benjamin Scott [mailto:[EMAIL PROTECTED]] Sent: Monday, April 29, 2002 10:19 AM To: Greater NH Linux Users' Group Subject: RE: Apache configuration question On Mon, 29 Apr 2002, at 10:11am, [EMAIL PROTECTED] wrote: Incorrect.
