As a side note I will try to test the worst case scenario in the Phoronix tests -- Postmark, and post the results here.
I managed to finish testing. As said above I picked up this test because it was the only one standing out with a great difference between the stock kernel and a selinux/audit configured kernel. It's also a very easy test to perform. The raw spreadsheet data and the conditions for the test may be found at ¹. I would really appreciate some help creating some nice graphs with this data. My conclusions so far: there's no difference between the stock -ARCH kernel and my -NOLSM build in which I disabled all LSMs (and hence audit). Note: the final test with 500000 files for the rotational disk isn't finished yet because... really... I shaved twice during the HDD tests. A side note regarding these tests: SSDs act according to their fame and HDDs are as misleading as a daily horoscope. I do plan to also test a no-debug but LSM enabled kernel even if it's just for the sake of statistics. ¹ https://dl.dropboxusercontent.com/u/29107946/linux-lsm/postmark-test.ods -- Arthur Țițeică
