You've probably already seen it, but just in case you missed it, there's
a "benchmarks" directory in the irregex upstream hg repo.
They mostly test the backtracking behaviour and some exponential regexes,
which might not necessarily be the things you're looking for.

Did you also try the irregex-based uri-generic code?  It's under
You can just feed it some URIs, which shouldn't be hard to find.
It's not particularly "heavy-duty" or slow, but it's real-world code
that does something useful.
