I have completed some stresstests (with up to 500 concurrent users) on Apache 2.0.59, mod_jk 2.1.20, Tomcat 5.5.17, using the following workers.properties:
<<< # Define 1 real worker using ajp13 worker.list=ajp13 # Set properties for worker1 (ajp13) worker.ajp13.type=ajp13 worker.ajp13.host=localhost worker.ajp13.port=8009 worker.ajp13.connection_pool_timeout=600 worker.ajp13.connection_pool_minsize=10 worker.ajp13.connect_timeout=15000 worker.ajp13.prepost_timeout=10000 >>> and this in the httpd.conf: <<< .... Timeout 300 KeepAlive On MaxKeepAliveRequests 100 KeepAliveTimeout 15 # WinNT MPM # ThreadsPerChild: constant number of worker threads in the server process # MaxRequestsPerChild: maximum number of requests a server process serves <IfModule mpm_winnt.c> ThreadsPerChild 250 MaxRequestsPerChild 0 </IfModule> .... >>> and it seems to be coping just fine now under the stressload. I think I'll use this setup on our live server now. Thanks a lot for your help. Just one final question: Despite my connection_pool_timeout=600 and connection_pool_minsize=10, one of the Apache2.exe processes remains at 70MB memory usage, even after the connection pool has gone down to 10 connections (verified by a netstat call). The good news is, the memory doesn't seem grow any further though. Still, keeping the 70MB for just the minimum 10 connections is a lot of cache memory. Maybe the connection pool releases timed out connections as expected, but doesn't flush them? BTW.: The mod_jk 1.1.20, downloaded from http://mirrors.dedipower.com/ftp.apache.org/tomcat/tomcat-connectors/jk/binaries/win32/jk-1.2.20/mod_jk-apache-2.0.58.so identifies itself as mod_jk/1.2.19, not as mod_jk/1.2.20 !
