no… I mean, in the benchmark are included all the cases where strncasecmp needs to be used.

Some PHP files that were on my server

As Benjamin suggested, here the best running times of "time phpunit" in the symfony test
suite:
With patch:
real 0m30.885s
user 0m14.713s
sys 0m2.123s
Without patch:
real 0m31.380s
user 0m14.865s
sys 0m2.170s
Seems that it is very similar (I have here variances of ±2 seconds…) So I think my patch
doesn't have a huge impact.
