Minimally, I see the same sort of hackbench socket performance regression as reported elsewhere (10-15% regression). Otherwise, it isn't particularly exciting results. The machine is very basic - 2 socket, 4 cores, x86-64, 2G RAM. Macine model is an IBM BladeCenter HS20. Processor is Xeon but I'm not sure exact what model. It appears to be from around the P4 times. Tests were based on three kernels. I used this tarball of scripts http://www.csn.ul.ie/~mel/projects/mmtests/mmtests-0.01-slabunified-0.01.tar.gz . The scripts have been pulled from all over the place with varying quality so try not cry too much if you look at scripts closely :) This tarball is capable of multiple different types of tests and was implemented in response to LSF/MM people asking for a suite to MM tests "of interest". I don't think a single suite is possible without taking a week to run a test but what is possible is to configure a bunch of tests to answer questions about a particular series (the tarball is capable of starting monitoring, profiling and running analysis after the fact to answer questions related to my own recent patch series). In this case, it's configured to run a number of benchmarks known to be sensitive to slab and page allocator performance. Roughly speaking, to test allocators the following happens 1. Configure 2.6.36-rc7 for SLAB, no other patches, build + boot 2. ./run-slabunified.sh slab-vanilla 3. Configure 2.6.36-rc7 for SLUB, no other patches, build + boot 4. ./run-slabunified.sh slub-vanilla 5. Configure 2.6.36-rc7 for SLUB, for-next and Christophs patches applied, build + boot 6. ./run-slabunified.sh unified-v4r1 (version 4 of patches, release candidate 1) 7. cd work/log 8. ../../compare-kernels.sh This should be enough to run a cross-section of tests against this series. Christoph, in particular while it tests netperf, it is not binding to any particular CPU (although it can), server and client are running on the local machine (which has particular performance characterisitcs of its own) and the tests is STREAM, not RR so the tarball is not a replacement for more targetting testing or workload-specific testing. Still, it should catch some of the common snags before getting into specific workloads without taking an extraordinary amount of time to complete. sysbench might take a long time for many-core machines, limit the number of threads it tests with OLTP_MAX_THREADS in the config file. I'm not going to go into details of how the scripts work - it's as-is only. That said, most test parameters are specified in the top-level config file with somewhat self-explanatory names and there is a basic README.
