Hi all,

My company run a CMS (typo3) on LAMP on RH linux.
Basically all users have same typo3 page as home page and thousands of users starts their browser every morning causing server very slow or even to hang (swap full because of too many apache processes)..

99% of the traffic is this home page which take 2s in a non busy time to be delivered.
I improve this time to 1.5s using php cache. Others mysql/apache tunning have so far not given me any significant improvement (I have been trhu web pages on apache/mysql tunning and test differents things).
As far I have seen mysql is ok and httpd processes are taking all cpu/mem.

My question is :
1 - As this home page (php page, 30K) in 99% of the traffic how can i improve the process not getting 1000 times the same request to my apache server.
I have no way to modify this home page policy, I can just work on the infrastructure side. I was thinking on some proxy/cache server but have no experience on that. Any efficient and open source solution ?

2 - Apart from php cache any hint to help me improve apache performance ?
I did not find anything else number of thread and related stuff in apache.
