Hello everyone, I have this funny problem. I have an installation of Apache communicating with Tomcat using mod_jk. (versions below) When accessing Tomcat directly for stress testing, i'm getting over 100 hits/sec. When i hit the site going thru Apache, I get 2 different results : 1. If i hit the site with 1 connection i get around 90 hits/sec (very good) 2. If i hit the site with multiple (1+) connections i get around 5 hits/sec (poor) I've compiled Apache as a worker MPM. I've made sure HostNameLookups are off. The virtual hosts are by IP and not NameVirtualHosts I'm connected straight into the network card when i run stress tests Here is the section that defines my worker configuration. <IfModule worker.c> StartServers 2 MaxClients 300 MinSpareThreads 25 MaxSpareThreads 75 ThreadsPerChild 25 MaxRequestsPerChild 10000 </IfModule> It seems like something is causing a bottleneck when i use more then 1 connection. When i compiled, i used the same script that we used on another production server. It doesn't have this issue. I hope someone can clarify what is going on. Apache 2.0.53 Tomcat 5.5.7 JK (mod_jk) 1.2.11 Thanks Joey
