- In which way are your system, web server, database and application configuration different from the defaults? Or phrased differently: what performance tweaks have you already tried?

Hi unSpawn,
I'm sending the replies of your questions and more information.
- The application isn't up to date we are developing the new version soon. And the server has available resources.
- We are using Cacti to monitor the server and there is no high usage of memory and CPU.
- The first page is a login page, which uses only some php includes to create the login page. Nothing about DB connections or something else and etc.
- The same system runs in all Virtual Hosts, first and second virtual hosts does not affected this kind of slow. For Example, if I open the page now, I can login and use the system. But if I try to make the same procedure in 30 minutes, the login page simply does show to me. Is something like a "render" issue, which doesn't happens with the other virtual hosts.
- There is nothing being generated in the logs. When this happens, the CPU and Memory usage still are low.
- For while I didn't made any changes in Apache to solve this, because I don't know too much of apache tunning.
Thanks a lot for the help!
