Performance measurement

onetick.py and OneTick provide some tools and classes to run the query and measure its performance.

measure_perf.exe

Function onetick.py.perf.measure_perf() can be used to call OneTick’s measure_perf.exe tool.

It runs specified query and prints the summary in the specified file.

Parsing summary

Classes onetick.py.perf.PerformanceSummaryFile and onetick.py.perf.MeasurePerformance can be used to parse contents of the summary file to python format.

Additionally, configuration parameter stack_info can be used to add some python debug information to the parsed result.
