What to do for a performance booster?

[cDGo]

We have a fast increase of usage on one of the websites.
It uses large amounts of PHP (1.3GB) and MySQL (1GB) resources.
So now I'm looking for tips on how to boost the performance of both to handle this traffic.
Maybe even starting with the ground rules to have a new and refreshed look at this matter.

Hello,

Cache as much as you can at a frontend, webserver, application levels. Search internet and forums for more details instructions on how to complete each of these levels.

LiteSpeed Web Server is definitely something to consider, depending on your budget.
