    All,
      I have been evaluating operating systems/filesystems for an upcoming
    web application service. Like most "web applications", it will rely
    heavily on the database and disk I/O. We have decided to use
    Postgresql for our database needs, but haven't finalized our OS
    choice. I have been testing the I/O performance of FreeBSD 5.3 and
    Fedora C3(XFS,EXT3). To be sure that I was using up to date versions
    of each OS I performed a cvsup and rebuilt the kernel (GENERIC) during
    the FBSD setup, and a yum update on the Linux install.

    Being fairly new to FreeBSD I was testing it as a matter of due
    diligence, however after using it for a few days it really started to
    grow on me. I was generally impressed with my overall experiance.
    However, after performing a number of I/O and Postgresql tests on
    different equipment, the performance proved to be considerably faster
    when using Fedora. Fedora with XFS was the clear performance winner
    in every test, followed by Fedora with EXT3, then FreeBSD. I was
    surprised to find such a dramatic difference between Fedora with XFS
    and FreeBSD. In almost every test Fedora(XFS) was dramatically
    faster performing the exact same operations on the same hardware. My
    best guess, is that FreeBSD 5.3 + updates is still in need of some
    performance tuning.

    Are there any good reasons for such a difference. Your thoughts are
    appreciated.

    Thanks!
