Usually there's always something that seems to 'break' a system. Tinkering or tweaking or an unexpected update.
Basically the LAMP web server at an office (CentOS 5.4) has started running Apache SSL connections really slowly. It seems that outside they are bit laggy but inside the office (on the same subnet) it is very slow taking sometimes 10-20 seconds just to load a page.
We have 2x DNS servers on that site (under Active Directory) that the clients are connected to but I'm unsure if that would affect the delays we face.
I've since (just in case) updated the kernel, etc on that box to see if it'd help. The mail server (similar setup) seems to be okay however. Only I have admin access to the server with an issue and the ONLY work done on it outside access to the web interfaces is me doing some PHP programming..
Any support would be great.
