Well I tested Reiser4 on systems building our Linux flavour (based on the T2 framework) thus with excessive software compilation, a lot of tarball extraction, compilation of fat packages such as linux, mozilla, openoffice et.al. and huge per-package ccache directories -> zilions of small files and did not encounter any abnormal behaviour aside the yet-to-be-fixed commit storms. Performance was superiour over ext3, XFS*, JFS or Reiser3 in this workload (that is less time "wasted" for FS housekeeping and the build finished noticable earlier). Patchset was tested around 2.6.1{4,5]. But I do not have the numbers around anymore and was basically waiting for Reiser4 to make it into the kernel to schedule further testing. You can see I'm not a blind Reiser4 follower but would rather like to see a fair chance for it. *) XFS oopsed so often in this test that I'll never touch it again ...
