RCU getting slower
Lynx,
we run 2 dual proc servers with 10k SCSI Raid 1. One is 1.2 dual and the other 1.5 dual procs. front end webserver with backend database server.
Problem is the massive php calls are too much for the webserver so we need to upgrade that server and offload all ads to a dedicated ad server and that will buy about 4 months at current growth. After that we go to load balancer and add servers as load increases.
All php files on the webserver are actually cached so they don't process with every page run (don't compile each time). This saves alot of heat but with 300,000 page views per day and upwards of 500 queries per second to the database it gets a little hot with the current hardware.
I'm close to final hardware selection and negotiations so once done I will migrate everything over asap and the speed will be again like day one.
