    Subject[BENCHMARK] tiobench 2.5.55 performance
    Date
    From
    Hi,
    Here are the results of comparison of kernel 2.5.55 and 2.5.54
    on TIObench. key findings are listed in the table. Values in the
    table indicate approximate percentage change with respect to previous result.
    Please see the mail in full window to see the formatted results.


    -------------------------------------------------------------
    test 2.5.55 (as compared to
    2.5.54) APPROXIMATE % change
    -------------------------------------------------------------
    rate (megabytes per second) no much change
    CPU % utilization 15% decrease
    Average Latency 15% decrease
    Maximum latency less than 10 % increase
    CPU efficiency 10% increase
    -------------------------------------------------------------

    No size specified, using 252 MB

    Unit information
    ================
    File size = megabytes
    Blk Size = bytes
    Rate = megabytes per second
    CPU% = percentage of CPU used during the test
    Latency = milliseconds
    Lat% = percent of requests that took longer than X seconds
    CPU Eff = Rate divided by CPU% - throughput per cpu load
