Hey all- I wasn't sure if I posted this correctly since I did it before my confirmation email from subscribing and it looked different in the archives. I'm looking for any ideas why my apache proxy would be causing such a huge performance hit to our web app. Thanks! :)

It is a VM with Fedora 13 installed. I am running a stand alone JIRA Tomcat installation on port 8080 and running httpd with mod_proxy as a reverse proxy on the same box. If I remove the httpd layer and go directly to Tomcat the performance is normal. When I add the httpd layer it slows down overall and hangs dramatically fairly often. I installed Wireshark and have captured some requests but I'm not really sure what I'm looking for. How can I tell what's going on in the time between some of the traffic going on? I also configured Flood but that doesn't seem to offer me any insight into what is causing the problem either. I'm likely not using these tools quite right but I can't seem to find out what I should be looking for. Here are my two VHosts. I am redirecting to HTTPS also, but if I take that layer out, it still has performance issues. <VirtualHost *:80> RewriteEngine On RewriteCond %{HTTPS} off RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} </VirtualHost> <VirtualHost 192.168.XXX.XXX:443> #<VirtualHost 192.168.XXX.XXX:80> ServerName 192.168.XXX.XXX ProxyRequests Off ProxyPreserveHost On SSLEngine On SSLCertificateFile /etc/httpd/ssl/jirassl-pem.crt SSLCertificateKeyFile /etc/httpd/ssl/jirassl.key ProxyPass / http://localhost:8080/ ProxyPassReverse / http://localhost:8080/ <Proxy *> Order deny,allow Allow from all </Proxy> </VirtualHost> Any suggestions insight into where i can find info to help me learn to debug issues with httpd in general would be greatly appreciated. Thanks all -Dustin Chesterman
