This was in August when preparing for LinuxCon, I tested netperf TCP_RR on 
two 64GB machines (one client, one server), four nodes each, with thread 
counts in multiples of the number of cores.  SLUB does a comparable job, 
but once we have the the number of threads equal to three times the number 
of cores, it degrades almost linearly.  I'll run it again next week and 
get some numbers on 3.6.
