epoll and performance

[Joachim Bauernberger]

Hi,

in the past i have seen several posts here that recommend an upgrade to epoll 
as a cure all performace issues.

Looking at the statistic on the dev epoll homepage after having a similar 
discussion with a friend I am now not so sure anymore whether epoll will be 
worth the hazzle for my setup.

I have 2 clients which implement Cache::Memcached as a fastcgi in apache. 
Those can be queried to talk to the memcache-servers running on the same 
hosts.

Since my (2) fastcgi clients use persistent tcp connections to talk to 
memchached I wonder whether the whole epoll stuff is really make a difference 
for me.

The way I understood epoll, is  it only boosts your performance if you have 
lots of connections that are established (and broken down again).

Maybe I understood epoll wrong? 
Please let me know if this is the case.

Thx & best regards,
