So, what I missed from this was:
I'm trying to get better benchmarks for the perl interpreter itself.
Lots of "one trick pony" type benchmarks exist, but very few that actually
try to look like they are doing typical things typical programs do, at the
typical scales real programs work out, so
Does the mighty hive mind of london.pm have any suggestions (preferably
useful) of what to use for benchmarking "typical" Perl programs?

Sadly things like regression tests *aren't* decent benchmarks because they're
a) trying to test corner cases, not common cases
b) trying to do this as efficiently as possible
As I'm still gainfully siphoning money from TPF to HMRC, I don't have an
employer from whom to derive test cases to turn into benchmarks.

Sadly not really. My fault for not asking a good enough question.
(Oooh. I managed to mention pony in context, quite unintentionally)
