Hi again,
I have tried nightly (pypy-c-jit-61992-6fe2c02099ef-win32) and still got boost:
code:
import time
class measure:
def __init__(self, description, size, runs):
self.description = description
self.size = size
self.runs = runs
def __enter__(self):
self.start = time.time()
def __exit__(self, *args):
elapsed = time.time() - self.start
print '%.2lf runs/sec, %s, size = %d, %d runs' % (self.runs /
elapsed,
self.description, self.size, self.runs)
def min_(arg):
seq = iter(arg)
try:
head = seq.next()
except StopIteration:
raise ValueError('arg is an empty sequence')
return reduce(min, seq, head)
N = 1000
N_max = 100000000
while N <= N_max:
K = 5 * N_max / N
r = range(N)
with measure('built-in', N, K):
for _ in range(K):
min(r)
with measure('with reduce', N, K):
for _ in range(K):
min_(r)
print
N *= 10
output:
372300.84 runs/sec, built-in, size = 1000, 500000 runs
692520.66 runs/sec, with reduce, size = 1000, 500000 runs
29994.00 runs/sec, built-in, size = 10000, 50000 runs
77279.74 runs/sec, with reduce, size = 10000, 50000 runs
4012.84 runs/sec, built-in, size = 100000, 5000 runs
7874.02 runs/sec, with reduce, size = 100000, 5000 runs
388.50 runs/sec, built-in, size = 1000000, 500 runs
791.14 runs/sec, with reduce, size = 1000000, 500 runs
30.79 runs/sec, built-in, size = 10000000, 50 runs
79.24 runs/sec, with reduce, size = 10000000, 50 runs
0.98 runs/sec, built-in, size = 100000000, 5 runs
7.90 runs/sec, with reduce, size = 100000000, 5 runs
