    All,
      I decided to join this list so that I could do a better job of
    staying on top of the I/O performance testing. I have moved my 5.3
    test server from RELENG_5_3 to RELENG_5 (2/2/05) and did some testing.
     I had almost identical results to my previous testing. Iostat
    indicates that I'm getting approximately 15Mb/sec on 5.x, and 58Mb/sec
    when I use 4.11. These figure are consistent on my current test
    boxes.
      1) Dell SC400, 256Mb Ram, 40Gb EIDE.
      2) Dell 4600, 512Mb Ram, 80GB EIDE.
    I also tested with NetBSD 2.0 and OpenBSD 3.6 and had similar
    performance to FreeBSD 4.11 (approx. 58Mb/Sec.)

    Note: EXT3 allows file sizes greater than 2Gb. I have created
    hundreds, if not thousands of them.
