RE: [squid-users] squid performance epoll. 350req/sec 100% cpu

Hi
 ok I learned the strace and it does call select (99% of time)
 
 looks like my epoll is not active :-((
 and I did found that I didn't compile it as I should.

But now I am unable to compile because of this errors.
 I don't have automake 1.5 (only 1.4 1.6 1.7 1.9)
And autoconf too
I do have debian stable... And added to it apt sources -> testing (to get
latest squid)

Can someone help tu run this?
I don't understand this whole think of automake autoconf

# this one later doesn't compile cleanly
# bootstrap.sh
