     Either I forgot (probable) or you didn't mention before (less probable)
that you had moved it to a newer machine.  Whatever you're running it on,
superpages or LINUX's "huge" pages ought to speed tor up considerably by
drastically reducing TLB misses.  (I wasn't suggesting that you revert to
older hardware.  I was thinking that you were still running tor on the Xeon-
based machine.)
