Python benchmarker / benchmarking framework
Project description
benchmark is a Python benchmarking framework, similar to Steve Purcell’s unittest in basic structure. It’s as simple as:
import benchmark import math class Benchmark_Sqrt(benchmark.Benchmark): each = 100 # allows for differing number of runs def setUp(self): # Only using setUp in order to subclass later # Can also specify tearDown, eachSetUp, and eachTearDown self.size = 25000 def test_pow_operator(self): for i in xrange(self.size): z = i**.5 def test_pow_function(self): for i in xrange(self.size): z = pow(i, .5) def test_sqrt_function(self): for i in xrange(self.size): z = math.sqrt(i) class Benchmark_Sqrt2(Benchmark_Sqrt): # Subclass the previous benchmark to change input using # self.setUp() label = "Benchmark Sqrt on a larger range" # The above label comes from the class name, this oen # comes from the label attribute each = 50 def setUp(self): self.size = 750000 if __name__ == '__main__': benchmark.main(format="markdown") # could have written benchmark.main(each=50) if the # first class shouldn't have been run 100 times.
which produces:
Benchmark Report ================ Benchmark Sqrt -------------- name | rank | runs | mean | sd --------------|------|------|------------------|------------------ pow operator | 1 | 100 | 0.00398081541061 | 0.000712735404794 sqrt function | 2 | 100 | 0.00518546819687 | 0.000691936907173 pow function | 3 | 100 | 0.00728440284729 | 0.00133268917025 Benchmark Sqrt on a larger range -------------------------------- name | rank | runs | mean | sd --------------|------|------|----------------|----------------- pow operator | 1 | 50 | 0.112720785141 | 0.00579241912336 sqrt function | 2 | 50 | 0.152897367477 | 0.0075897918245 pow function | 3 | 50 | 0.211021671295 | 0.0139702154247 Each of the above 450 runs were run in random, non-consecutive order by `benchmark` v0.1.2 (http://jspi.es/benchmark) with Python 2.7.1 Darwin-11.3.0-x86_64 on 2012-04-17 16:39:10.
