除了缓存之外，如何在LAMP服务器上使用更多的内存而不是CPU时间？

Question

My site is rough on cpu usage, but I have plenty of memory (and hdd space) I could be using. The site is sort of a game with lots of db updates and object manipulations. Generally speaking, is there any other way to share the load after having cached as much as I think I can?

Thanks

There is no general advice I, am afraid.
Can't you at least roughly profile your application, to determine certain bottlenecks - if it's db updates, or object manipulations? Or even some other, obscure matter?

If your filesystem is a cheap one (not SAS), and there are many disk I/O, it may eat up your CPU easily. You have to optimize disk writes, but I am afraid again there is no common way. Try to reduce number of indexes. Cache your database in memory, when applicable.
