There is a plan going forward to have more automated performance benchmarking linked to git, especially so that performance improvements (or regressions) can be quantified as they happen. The hardware has been ordered, but it will take a while to get this kind of automation up and running.
However, if you want up-to-date PCRE benchmarks and performance tracking you should also be talking to the PCRE folks. Maybe they have more recent data already.
