a small utility for benchmarking
Project description
Benchmarker is a small utility to benchmark your code.
See CHANGES.txt for details of changes and enhancements.
Example (ex.py):
def fib(n): return n <= 2 and 1 or fib(n-1) + fib(n-2) from benchmarker import Benchmarker bm = Benchmarker(30) # or Benchmarker(width=30, out=sys.stderr, header=True) ## Python 2.5 or later with bm('fib(n) (n=33)'): fib(33) with bm('fib(n) (n=34)'): fib(34) with bm('fib(n) (n=35)'): fib(35) ## Python 2.4 bm('fib(n) (n=33)').run(fib, 33) # or .run(lambda: fib(33)) bm('fib(n) (n=34)').run(fib, 34) # or .run(lambda: fib(34)) bm('fib(n) (n=35)').run(fib, 35) # or .run(lambda: fib(35)) ## print compared matrix bm.print_compared_matrix(sort=False, transpose=False) # or print(bm.compared_matrix())
Output:
$ python ex.py utime stime total real fib(n) (n=33) 1.890 0.000 1.890 1.900 fib(n) (n=34) 3.030 0.010 3.040 3.058 fib(n) (n=35) 4.930 0.010 4.940 4.963 --------------------------------------------------------------- real [01] [02] [03] [01] fib(n) (n=33) 1.900s - 60.9% 161.2% [02] fib(n) (n=34) 3.058s -37.9% - 62.3% [03] fib(n) (n=35) 4.963s -61.7% -38.4% -
