Hi Adrian,

Thanks for your reply and suggestions as always.

This was one of my first experimental freebsd proxy server. I had
enabled all 3 of the above compilation options thinking that I would
have a choice of 3 instead of 1!:)

But my question is: does it degrade the performance of Squid? If I just
use enable-kqueue, will it give a performance boost?

Thanking you...
