I am closely following kernel.org stable-queue. Today I am feeling some performance regression running
linux-3.6.9-rc1

But it is just a feeling. I need some sensible hint howto begin with performance testing!
phoronix-testsuite?

Well, it depends a lot on which performances you want to measure on which kind of kernel.

The phoronix test suite looks like a gas factory to me.

This is what I rely on :

1/ Sysbench (thread and mutex tests) for global scheduler / multithreading efficiency
2/ IOZone for Disk IO thoughput
3/ Interbench for scheduler latency

BTW... I do confirm performance regressions with early 3.6 (That started with 3.5)
And... if upstream wants to solve the "kernel mount slow" problem with the ideas they get then... I fear about 3.7...

That is my motivation to ask :)

linux-3.6.8 is running perfectly for me!
