I haven't looked at the patches, so I don't know of a specific place to look for a slowdown, but I thought it might help to perform the same query tests as my most recent test for evaluating qsort variants (some description in [1]), and here is the spreadsheet. Overall, the differences look like noise. A few cases with unabbreviatable text look a bit faster with the patch. I'm not sure if that's a real difference, but in any case I don't see a slowdown anywhere.
