Atri ran some quick n dirty tests to see if there were any regressions. He benched a large scan followed by vacuum. So far, results are inconclusive so better testing methodologies will definitely be greatly appreciated. One of the challenges with working in this part of the code is that it's quite difficult to make changes without impacting at least some workloads.
I'm adding something to pgbench-tools to test for some types of vacuum regressions that I've seen before. And the checksum benchmarking I've already signed up for overlaps with this one quite a bit. I'd suggest reviewers here focus on code quality, correctness, and targeted optimization testing. I'm working heavily on a larger benchmarking framework that both this and checksums will fit into right now.
