Tor is not aggressive enough about improving latency

Summary: Please make Tor more aggressive in detecting when it is using a slow OR path and hence causing it to test out alternate paths.

I've noticed that some Tor ORs are faster than others. The end result is that sometimes I get 'bum' ORs who slow my system down to a crawl. Tor does not seem to be nearly aggressive enough about detecting this situation and trying alternate routing paths.

I recognize that if Tor was more aggressive about finding better paths a really smart attacker could use DOS attacks against specific ORs to shape traffic into specific proxies but ya gotta admit that's a pretty esoteric attack. For the moment I think performance is more important.

I also recognize that if Tor is too aggressive in optimizing the routing path then better performing ORs will get slammed but that is a self correcting problem.

Please considering adding features to make Tor more aggressive in finding better ORs. The biggest thing keeping me from recommending Tor to all of my friends is the latency it introduces.

Thanks for the input. Yeah, we're always trying to make it faster. I'll keep this one in the bug report to remind us to keep looking at more speed work.

flyspray2trac: bug closed.
Tor has some approaches to dealing with this, like load balancing over routers based on measured bandwidth. We need more. But this isn't a bug per se. It's just an item on the ongoing todo list.
