I have a client that needs his server optimized. We also may need to setup some memory caching. I'm not sure if this has to be done in the PHP application, if so, you tell me what to do and I'll do it.
His server is Hetzner EX10: http://www.hetzner.de/en/hosting/produkte_rootserver/ex10
He also has his OS and mysql in a SSD.
He's using cPanel + Litespeed web server.
The memory usage is currently 14GB and server load is 10.
We want to cache the php pages and mysql in the memory and lower the load and loading time of the pages.
Please PM.
