When I was operating an exit node...
Maybe I mis-read your original post, but I thought you *were* running an exit node. That's really the only scenario that requires a lot of name resolutions. An entry or middle nodes doesn't need much DNS traffic because they are only passing along packets.
An exit node with a lot of connections needs lots of name resolutions, making fast DNS a necessity. Whether that's accomplished with a local caching name server or some nearby name server depends on the resources you have available to you.

Interesting, that's news to me. When I was operating an exit node I remember such log entries popped up on a regular basis. I also thought the CPU was the bottleneck, but still tried tweaking things; a rather unsuccessful quest. It just never occured to me DNS might be an issue.
Do you have a link to further read up on things? Is this a FAQ by now? And what's the solution; running a local caching nameserver? Thanks.
