Hi Jose,
thank you for the feedback.
We took your remarks into account and we are doing some perfs with
iozone (close to desktop activity, mono-thread) and ffsb (allows to run
benchs
in a multi-thread activity like a server does, different blocks sizes...).
We compare ext3 and ext4 (with extents, w/ and w/o del alloc...)...
We will publish the results on bullopensource.org
Hi Jean-Pierre,
While it may be to late for the purposes of your OLS paper, one thing
that doesn't seem to be getting much attention is the performance of a
file system while doing many meta-data operations or throughput testing
during heavy journal log activity. I believe that IOzone is very
limited in testing this and FFSB isn't much better at it either.
Eventually, I plan to add support in FFSB to create workload profile
were one can select a weight balance of these types of operations.
Is this something that you are already doing for this round of testing?
