I built the Tor binary myself, statically-linked against builds of the latest library versions: openssl, libevent, and zlib. I'm also using the OpenBSD malloc that comes with the Tor tarball.

BTW, the openssl performance is twice that of the old version that comes with CentOS v5.x!

I doesn't seem likely that rebuilding the kernel will yield much benefit, and I don't see that Tor relies much on external libraries.

Thanks for the response.

Tons of things, recompiling, optimizing the OS, updating libevent, running multiple daemons.

For some good guides on howto run a faster exit node, look at: https://www.torservers.net/wiki/setup/server and poke around that site to see more suggestions.

I have a machine that is dedicated to being a Tor exit node. How can
I maximize the performance (high throughput / low latency) of Tor
traffic?

I have plenty of under-utilized CPU and RAM resources on this
system. According to TorStatus, my bandwidth is rarely maxed-out.

This is on a Linux system, currently running Tor v0.2.2.30-rc.

So... what resources can I spend to make this a better Tor node?

Thanks.
