[issue8064] Large regex handling very slow on Linux

[STINNER Victor]

STINNER Victor <victor.stinner at haypocalc.com> added the comment:

Results on Linux (Debian Sid) with different Python versions:
 * Python 2.4.6: 14112.8 ms
 * Python 2.5.5: 14246.7 ms
 * Python 2.6.4+: 14753.4 ms
 * Python trunk (2.7a3+): 69.3 ms

It looks like re engine was optimized in trunk :-)

Note: I replaced stopwatch by time.time() and used 100 iterations instead of 500 iterations. Values are not important, only the ratio between the different results.

sys.maxunicode should be different on the two OS.
