It looks like you have some code that hogs memory, and you'll need to control it somehow. Most people have servers more in the range of 10-40MB, with a bunch of that shared. - Perrin

Im sorry that was a mistake the non modeperl apache is like this: 125 nobody 0 0 3960 0 SW0.0 0.0 5:58 httpd 126 nobody 0 0 2960 0 SW0.0 0.0 0:19 httpd 127 nobody 0 0 804 608 504 S 0.0 0.2 8:10 httpd 128 nobody 0 0 888 724 592 S 0.0 0.2 11:21 httpd 129 nobody 0 0 872 712 592 S 0.0 0.2 5:21 httpd John
Re: Again, Modperl running scripts slower than non-modperl!?
It actually get alot larger than that! Anywho, yes i have installed the latest libpreq, latest modperl, perl 5.6.1, apache 1.3.20 and on linux 2.2.19 Hope that helps. John 200 Megs for a modperl process sounds way off. Are you using an old version of libapreq? There is a big memory leak with older versions, particulary for multipart file uploads. Try http://www.apache.org/~jimw/libapreq-0.33.tar.gz and see if that fixes things up. Also you didn't say what version of modperl,perl,apache or what platform you are using, so I am probably way off. Heh, I'm just taking a wild ass guess. On Saturday, August 4, 2001, at 11:29 PM, John Buwa wrote: > Ok guys, > > Here goes again ...

That kills your performance always. Could you run your test on a different machine or temporarily switch off the regular server? Trying to run close to 200 Mbyte modperl Apaches on a 256 Mbyte machine is not going to work. Have you looked at MaxRequestsPerChild? But even the non-modperl servers at 30 Mbyte size seems ridiculously large: are you sure you need all the modules that you compiled into Apache? Elizabeth Mattijsen
Again, Modperl running scripts slower than non-modperl!?
Ok guys, Here goes again ... To refresh the standing: I am running my scripts on regular apache as the active server to the public. I am porting over my scripts to work properly with the modperl enable apache server. To do this when i am working on scripts and testing them, i start the modperl server running on another port as to not interfere with the port 80 requests. If i run the same script on each apache the non apache will load and i can reload it again, before the original requested script completes on the modperl server. I wanted to convert to modperl for faster performance on my perl scripts, but i can not get that faster performance its several times worse than the nonperl server??? Now i know no one here is physic (Or maby i am wrong) but for those who are not i need to give you some clues. Here is a print out from top: 91 processes: 89 sleeping, 2 running, 0 zombie, 0 stoppedCPU states: 0.0% user, 0.7% system, 0.0% nice, 99.2% idleMem: 257408K av, 228384K used, 29024K free, 13744K shrd, 5380K buffSwap: 265528K av, 184780K used, 80748K free 8908K cached PID USER PRI NI SIZE RSS SHARE STAT %CPU %MEM CTIME COMMAND25788 nobody 0 0 126M 125M 1076 S 0.0 49.8 0:13 httpd
