The following page has been changed by RichardDing: http://wiki.apache.org/pig/PigMultiQueryPerformanceSpecification ------------------------------------------------------------------------------ * Execute these stores one by one * Get all remaining stores and execute them in at once + [[Anchor(Performance Results)]] + == Performance Results == + + We have run the PigMix suite on a Hadoop cluster to compare this enhancement to the code in the trunk. Here are the results (average over 3 runs): + + ||Test Case||Trunk||MultiQuery || + ||L1 ||4min07sec||4min10sec|| + ||L2||1min46sec||1min54sec|| + ||L3||5min12sec||4min40sec|| + ||L4||2min39sec||2min36sec|| + ||L5||2min15sec||2min14sec|| + ||L6||2min27sec||2min28sec|| + ||L7||2min14sec||2min06sec|| + ||L8||2min07sec||2min01sec|| + ||L9||8min58sec||8min42sec|| + ||L10||9min10sec||9min15sec|| + ||L11||3min23sec||3min28sec|| + ||L12||10min14sec||2min47sec|| + + L12 is the only multi-query script in the suite and we see 70% performance improvement. For the non-multi-query scripts, the performance is unchanged. + +
