Linux is definitely ok. And your system is fine as well. Sure about taking a look at your sysctl.conf.

and with reason, I think... Among all opensource ones, this is really THE accomplished one. Add to that the fact that Willy focuses a lot on the queue logic - which is essential if you're talking about throttling and managing the number of connections that you want to establish to different backends... HTTP handling is not all there yet (i'm working on various custom patches even as we speak - only my 'connslots' patch has been released [and accepted by Willy] publicly so far) - but it's fair for basic ("basic" being relative!!!) needs.
