Hello Nicholas, Thanks for your kind response. Yes, the storage engine is mysql and it is actually typo3 powered site. But I have already done the optimization in mysql level and there is no such load on mysql. The server is armed with 4 GB Ram and quadcore processor. When the site becomes slow ; the top shows it is actually apache which consumes so much CPU. Is not there any way to optimize apache ?
