Subject [GitHub] accumulo issue #257: ACCUMULO-4636 system iterator improvements for 1.7
Date Wed, 17 May 2017 20:19:48 GMT
Github user milleruntime commented on the issue:
    Refactored the benchmark suite to build different version.  Here are the new results:
    Test: MyBenchmark.seekAllSystemIters10 showed 89.8% increase in ops/s
    Test: MyBenchmark.seekAllSystemIters1000 showed 93.8% increase in ops/s
    Test: MyBenchmark.seekTestWithCQFilter10 showed -13.4% increase in ops/s
    Test: MyBenchmark.seekTestWithCQFilter1000 showed 4.2% increase in ops/s
    Test: MyBenchmark.seekTestWithCfFilter10 showed 35.7% increase in ops/s
    Test: MyBenchmark.seekTestWithCfFilter1000 showed 63.3% increase in ops/s
    Test: MyBenchmark.seekTestWithEmptyAuths10 showed 112.1% increase in ops/s
    Test: MyBenchmark.seekTestWithEmptyAuths1000 showed 199.9% increase in ops/s
    Total average 73.17% increase in ops/s
    The one scenario still seems to show some regression, seekTestWithCQFilter, which seeks
to data with a Column Qualifer.  I am not sure why this is happening... perhaps the extra
checks added in ColumnQualifierFilter cause a slight slowdown when a CQ is present?
