Siddhesh Poyarekar 0cd2828695 benchtest: script to compare two benchmarks ... This script is a sample implementation that uses import_bench to construct two benchmark objects and compare them. If detailed timing information is available (when one does `make DETAILED=1 bench`), it writes out graphs for all functions it benchmarks and prints significant differences in timings of the two benchmark runs. If detailed timing information is not available, it points out significant differences in aggregate times. Call this script as follows: compare_bench.py schema_file.json bench1.out bench2.out Alternatively, if one wants to set a different threshold for warnings (default is a 10% difference): compare_bench.py schema_file.json bench1.out bench2.out 25 The threshold in the example above is 25%. schema_file.json is the JSON schema (which is $srcdir/benchtests/scripts/benchout.schema.json for the benchmark output file) and bench1.out and bench2.out are the two benchmark output files to compare. The key functionality here is the compress_timings function which groups together points that are close together into a single point that is the mean of all its representative points. Any point in such a group is at most 1.5x the smallest point in that group. The detailed derivation is a comment in the function. * benchtests/scripts/compare_bench.py: New file. * benchtests/scripts/import_bench.py (mean): New function. (split_list): Likewise. (do_for_all_timings): Likewise. (compress_timings): Likewise.		2015-06-01 23:14:11 +05:30
