You re-used the old keys? Blutmagie retained its guard status.

New TORy0 currently has the same 11000KB/16000KB limits as blutmagie and runs
only one TOR instance. After a couple of days, one core uses ~12% CPU on one
core for only 1500 TCP connects as an exitnode with ample memory.

But it will get serious soon enough. ;)
