You didn't give a lot of details, so some (general) possibilities:

1. Using PHP opcode caching. See: APC, xcache, Zed

2. Use a separate static media server for all static media.

3. Play with MaxChildren/MaxClients and the related options.

4. It's possible you are simply getting too many visitors. Upgrade to a faster machine, or load balance between multiple app servers.
