I suspect it'll be a noticeable difference, maybe a big one. Most of the Libevent performance improvements I've heard of involve systems with many connections, and exit nodes have thousands. > If you managed to build Tor on -stable with libevent 2.x from ports > I'm also happy to try any custom patches you might have applied. It may be easier to get upstream to use pkg-config first. I'm planning to look at their autoconf script and open a ticket today. That said, I think they're phasing out Libevent 1.x support, so we can't wait too long.
