On an 8p 2.6.24-rc2 I see even a 50% regression on tbench SLAB vs. SLUB
when specifying 8 threads.
Interestingly nothing changes the performance numbers regardless of
debugging on or off etc etc. Usually debugging should reduce performance
but nada. May have something to do with the localhost interface? Something
is effectively throttling SLUB here.
2.6.23 SLUB 2159.62 MB/sec
2.6.24-rc2-slab head SLUB 1260.80 MB/sec
2.6.24 SLUB should be faster than 2.6.23 SLUB. Still trying to figure out
what is going on....
