They're on the NIC.  I tried moving one of them to lo0 (made sure
forwarding was enabled) and saw essentially no difference.  Average
ping time went slightly down, but well within standard deviation, so
it may have been a fluke.  Mysql performance was neither worse nor
better.

There are only ~1000:
