You have not tried enough tests ;-).
On my Win7-64 system:
from timeit import timeit
print(timeit(" 'a'*10000 "))
3.3.0b2: .5
3.2.3: .8
print(timeit("c in a", "c = '…'; a = 'a'*10000"))
3.3: .05 (independent of len(a)!)
3.2: 5.8 100 times slower! Increase len(a) and the ratio can be made as
high as one wants!
print(timeit("a.encode()", "a = 'a'*1000"))
3.2: 1.5
3.3: .26
Similar with encoding='utf-8' added to call.
Jim, please stop the ranting. It does not help improve Python. utf-32 is
not a panacea; it has problems of time, space, and system compatibility
(Windows and others). Victor Stinner, whatever he may have once thought
and said, put a *lot* of effort into making the new implementation both
correct and fast.
On your replace example
>>> imeit.timeit("('ab…' * 1000).replace('…', '……')")
> 61.919225272152346
>>> timeit.timeit("('ab…' * 10).replace('…', 'œ…')")
> 1.2918679017971044
I do not see the point of changing both length and replacement. For me,
the time is about the same for either replacement. I do see about the
same slowdown ratio for 3.3 versus 3.2 I also see it for pure search
without replacement.
print(timeit("c in a", "c = '…'; a = 'a'*1000+c"))
# .6 in 3.2.3, 1.2 in 3.3.0
This does not make sense to me and I will ask about it.
