3 PYBENCH - A Python Benchmark Suite
6 Extendable suite of low-level benchmarks for measuring
22 The command line interface for pybench is the file pybench.py. Run
23 this script with option '--help' to get a listing of the possible
28 Micro-Manual
29 ------------
31 Run 'pybench.py -h' to see the help screen. Run 'pybench.py' to run
32 the benchmark suite using default settings and 'pybench.py -f <file>'
35 It is usually a good idea to run pybench.py multiple times to see
36 whether the environment, timers and benchmark run-times are suitable
39 You can use the comparison feature of pybench.py ('pybench.py -c
41 reference run.
48 inconsistent. Examples include: web-browsers, email clients, RSS
52 use the filtering option, e.g. 'pybench.py -t string' will only
53 run/show the tests that have 'string' in their name.

332 ---------------
336 - made timer a parameter
337 - changed the platform default timer to use high-resolution
340 - added option to select timer
341 - added process time timer (using systimes.py)
342 - changed to use min() as timing estimator (average
344 - garbage collection is turned off per default
345 - sys check interval is set to the highest possible value
346 - calibration is now a separate step and done using
349 - modified the tests to each give a run-time of between
350 100-200ms using warp 10
351 - changed default warp factor to 10 (from 20)
352 - compared results with timeit.py and confirmed measurements
353 - bumped all test versions to 2.0
354 - updated platform.py to the latest version
355 - changed the output format a bit to make it look
357 - refactored the APIs somewhat
