How to fully utilize resources for relay?
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.
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. -Andrew On Tue, Aug 2, 2011 at 8:37 PM, Steve Snyder <swsnyder@snydernet.net> wrote:

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.

Hi Steve, It can take a long time until a Tor relay picks up larger amounts of traffic. Also, the more ports you allow to exit, the more often your relay will be picked as part of a circuit. On 03.08.2011 03:21, Steve Snyder wrote:
