The "PigMix" page has been changed by AlanGates. http://wiki.apache.org/pig/PigMix?action=diff&rev1=11&rev2=12 -------------------------------------------------- || PigMix_12 || 156 || 160.67 || 0.97 || || Total || 2440.67 || 2001.67 || 1.22 || + Run date: October 18, 2009, run against top of trunk as of that day. + With this run we included a new measure, weighted average. Our previous multiplier that we have been publishing takes the total time of running all 12 Pig Latin scripts and compares it to the total time of + running all 12 Java Map Reduce programs. This is a valid way to measure, as it shows the total amount of time to do all these operations on both platforms. But it has the drawback that it gives more weight to + long running operations (such as joins and order bys) while masking the performance in faster operations such as group bys. The new "weighted average" adds up the multiplier for each Pig Latin script vs. Java + program separately and then divides by 12, thus weighting each test equally. In past runs the weighted average had significantly lagged the overall average (for example, in the run above for August 27 it + was 1.5 even though the total difference was 1.2). With this latest run it still lags some, but the gap has shrunk noticably. + + || Test || Pig run time || Java run time || Multiplier || + || PigMix_1 || 135.0 || 133.0 || 1.02 || + || PigMix_2 || 46.67 || 39.33 || 1.19 || + || PigMix_3 || 184.0 || 98.0 || 1.88 || + || PigMix_4 || 71.67 || 77.67 || 0.92 || + || PigMix_5 || 70.0 || 83.0 || 0.84 || + || PigMix_6 || 76.67 || 61.0 || 1.26 || + || PigMix_7 || 71.67 || 61.0 || 1.17 || + || PigMix_8 || 43.33 || 47.67 || 0.91 || + || PigMix_9 || 184.0 || 209.33 || 0.88 || + || PigMix_10 || 268.67 || 283.0 || 0.95 || + || PigMix_11 || 145.33 || 168.67 || 0.86 || + || PigMix_12 || 55.33 || 95.33 || 0.58 || + || Total || 1352.33 || 1357 || 1.00 || + Weighted Average: 1.04 == Features Tested ==
