partitionedtables (each with 1000 partitions) being joined, planning time is measured 10 consecutive times. For this
setof 10 runs we calculate average and standard deviation of planning time. Such 10 sets are sampled. This means
planningtime is sampled 100 times in total with and without patch respectively. Measurements with master and patched
arereported in the attached excel sheet.
Well, this is fine then I guess, but if the original results weren't
stable enough for people to draw conclusions from, then it's better
not to post them, and instead do this work to get results that are
stable before posting.
