Update performance numbers due to #10482

The fix in 0b7e538a has regressed these benchmarks. I have recentered
them rather than marking them as broken(10482), because nobody
systematically watches the broken test cases, and we want to catch
future regressions (or improvements!). #10482 is currently still open,
presumably because this needs investigating.
