Christoph,
We tested SLUB on a 2 socket Clovertown (Core 2 cpu with 2 cores/socket) and a 2 socket Woodcrest (Core2 cpu with 4 cores/socket).
We found that for Netperf's TCP streaming tests in a loop back mode, the TCP streaming performance is about 7% worse when SLUB is enabled on 2.6.21-rc7-mm1 kernel (x86_64). This test have a lot of sk_buff allocation/deallocation.
For Volanomark, the performance is 7% worse for Woodcrest and 12% worse for Clovertown.
