________________________________________________________________________ ANNOUNCING: pybench -- The Python Benchmark Suite Version 1.0.0 Extendable suite of of low-level benchmarks for measuring the performance of the Python implementation (interpreter, compiler or VM). ________________________________________________________________________ WHAT IS IT ?: pybench is a collection of tests that provides a standardized way to measure the performance of Python implementations. It takes a very close look at different aspects of Python programs and let's you decide which factors are more important to you than others, rather than wrapping everything up in one number, like the other performance tests do (e.g. pystone which is included in the Python Standard Library). pybench has been used in the past by several Python developers to track down performance bottlenecks or to demonstrate the impact of optimizations and new features in Python. There's currently no documentation and no distutils support in pybench; that'll go into one of the next releases. For now, please read the source code. The command line interface for pybench is the file pybench.py. Run this script with option '--help' to get a listing of the possible options. Without options, pybench will simply execute the benchmark and then print out a report to stdout. Here's some sample output: """ Tests: per run per oper. overhead ---------------------------------------------------------------------- BuiltinFunctionCalls: 131.50 ms 1.03 us 0.50 ms BuiltinMethodLookup: 195.85 ms 0.37 us 1.00 ms CompareFloats: 126.00 ms 0.28 us 1.00 ms CompareFloatsIntegers: 201.05 ms 0.45 us 0.50 ms CompareIntegers: 192.05 ms 0.21 us 2.00 ms CompareInternedStrings: 117.65 ms 0.24 us 3.50 ms ...

This release includes a few more tests and extends the range of supported Python versions to 1.5.x - 2.2. It is also the first publically announced new version of pybench in years. ________________________________________________________________________ WHERE CAN I GET IT ? The download archive of the package can be found at: http://www.lemburg.com/files/python/ ________________________________________________________________________ WHAT DOES IT COST ? pybench comes with a Python style license, which means that you can use them in both commercial and non-commercial settings without fee or charge. It comes with full source code. ________________________________________________________________________ WHERE CAN I GET SUPPORT ? Commercial quality support for this package is available from eGenix.com Software GmbH in form of support tickets.
