What makes you think git doesn't?

git has a large variety of options for selecting order and subset and
relation of what to output to the log.

It is still fast, even while doing rename/copying detection on the fly.

I suggest you actually check your beliefs against the actual program.
"The reason the other software is faster must be because it sucks in
comparison to ours." is a fallacy.  git has been developed by a set of
kernel-savvy developers working on a large code base with a necessity
for high speed (Linus merges several hundred patches from different
repositories daily).
