I released Benchmarker ver 4.0.0 http://pypi.python.org/pypi/Benchmarker/ http://pythonhosted.org/Benchmarker/
Benchmarker is a small utility to benchmark your code. *NOTICE* This release doesn't have compatibility with ver 3.x. Installation ------------ $ sudo pip install Benchmarker Example ------- example.py:: from benchmarker import Benchmarker with Benchmarker(1000*1000, width=20) as bench: s1, s2, s3, s4, s5 = "Haruhi", "Mikuru", "Yuki", "Itsuki", "Kyon" @bench(None) def _(bm): for _ in bm: ## empty loop pass @bench("concat") def _(bm): for _ in bm: s = s1 + s2 + s3 + s4 + s5 @bench("join") def _(bm): for _ in bm: s = "".join((s1, s2, s3, s4, s5)) @bench("format") def _(bm): for _ in bm: s = "%s%s%s%s%s" % (s1, s2, s3, s4, s5) Output example:: $ python example.py -h # show help message. $ python example.py # or python example.py -n 1000000 ## benchmarker: release 4.0.0 (for python) ## python version: 3.4.1 ## python compiler: GCC 4.2.1 Compatible Apple LLVM 6.0 (clang-600.0.51) ## python platform: Darwin-14.0.0-x86_64-i386-64bit ## python executable: /usr/local/bin/python ## cpu model: Intel(R) Core(TM) i7-4650U CPU @ 1.70GHz ## parameters: loop=1000000, cycle=1, extra=0 ## real (total = user + sys) (Empty) 0.0335 0.0300 0.0300 0.0000 concat 0.4192 0.4200 0.4100 0.0100 join 0.3674 0.3700 0.3700 0.0000 format 0.4765 0.4600 0.4600 0.0000 ## Ranking real join 0.3674 (100.0) ******************** concat 0.4192 ( 87.6) ****************** format 0.4765 ( 77.1) *************** ## Matrix real [01] [02] [03] [01] join 0.3674 100.0 114.1 129.7 [02] concat 0.4192 87.6 100.0 113.7 [03] format 0.4765 77.1 88.0 100.0 Notice that empty loop times (real, user, sys and total) are subtracted from other benchmark times automatically. For example:: =================================================== benchmark label real (second) --------------------------------------------------- join 0.3674 (= 0.4009 - 0.0335) concat 0.4192 (= 0.4527 - 0.0335) format 0.4765 (= 0.5100 - 0.0335) =================================================== See http://pythonhosted.org/Benchmarker/ for details.
