Comment (by teor):

 Still working on the best advice to give.

 Here's a MaxMemInQueues setting that's easier to understand:

 Set MaxMemInQueues to half your available RAM per tor instance.
 (It doesn't track all of Tor's memory usage.)

 If your machine has one relay, if you have this much RAM, try this
 setting:
 4 GB -> MaxMemInQueues 512 MB
 8 GB -> MaxMemInQueues 2 GB
 16 GB -> MaxMemInQueues 4 GB
 32 GB -> MaxMemInQueues 8 GB

 (If you have more than one relay on the machine, divide MaxMemInQueues by
 the
 number of relays. If you still have RAM issues, take down one relay.)

 Here's a list of other options relay operators can use for load tuning,
 probably appropriate for a wiki page:
