I just wanted to get a sense of how many people share this "Git

Count me as one of them. Git is all about speed, and C is the
best choice
for speed, especially in context of Git's workload.
Nono, hand-optimized assembly is the best choice for speed. C is
just
a little more portable ;-)
I have a buck here that says that you cannot hand-optimise
assembly (on modern processors at least) as good as even gcc.

I win. Donate $1 to FSF next time you get the opportunity ;-)
Well, you picked a very specific algorithm amenable to that kind of
optimization: small, manageable, with a minimal and well-defined
performance critical section that could be written in assembly. Note
how a good chunk of the implementation was still in C. At most I'd
give you 75 cents for that one. ;-)
