I thought my setting were high enough to do more around 3000

Increase the spare servers value; what happened here (as far as I can see) is that too many requests arrived at once and Apache couldn't fork fast enough to keep up.

Of course, if you served 1.7GB in six minutes, you can probably afford to get another server; and with a cpu load of above 20% you'll have to do that pretty soon anyway.

I can't even telnet in. I guess I have to reboot it =/

I rebooted and got in. This look good?

Did you change the HARD_SERVER_LIMIT in httpd.h and recompile before setting the MaxClients to 3000?

http://httpd.apache.org/docs/mod/core.html#maxclients

Yeah I think it's even set higher than that. I run freebsd I think I have to set it higher in lint

options "PMAP_SHPGPERPROC=201"

201 to 1000?

don't expect much from apache (at least version 1.3.x) when you have many connections. It has been know apache's performance drops drastically beyond 150 concurrent httpd connections. A free solution, thttpd might be a much better solution for busy sites, but it has its own lilmitations with php, etc. Zeus webserver will be much better alternative, but it's also much more expensive.

what about apache 2.0? do you know if it performs well with a lot of connections etc?

How do I install thttpd over apache? I don't think much php is in use

I have never used thttpd myself since we rely heavily on php. But you can donwload thttpd and see how to install it here (http://www.acme.com/software/thttpd/). For a web server comparison/benchmark, check it out here (http://www.acme.com/software/thttpd/benchmarks.html).

Have you tried apache 2.0? I am not sure whether apache 2.0 will suffer the same problem as apache 1.3.x for high number of simultaneous httpd connections. Hopefully not ...

also, I have read it somewhere (can't find it again) where people use both apache and thttpd where apache serves mostly php/dynamic contents and thttpd serves mainly static contents. I am still have to learn how to do this.

This url (http://php.weblogs.com/tuning_apache_unix) might be usefull ...

There is also the tux web server, serving directly from kernel, lighting fast.

But only static content is supported. Still, maybe worth a look to use with apache to achieve better performance.

I think I know the reason why now =/ It's the hard limit for plesk
