3.20GHz 4 core and 16 g.b ram running onCentOS release 5.9 (Final) upload
and download via php scripts like rapidshare 

the problem is i have high connections on this server and i want to know how
could i configure the nginx correctly

 worker_connections  51200; # you might need to increase this setting for
busy servers
 use epoll; #  Linux kernels 2.4.x  change to rtsig
}
