in thread Much slower DBI on RHEL6

That's exactly right. Perl 5.10.0 accidentally disabled a list assignment optimization. Perl 5.10.1 re-enabled that optimization and a lot of functions which perform list assignment from @_ run faster under 5.10.1 than they did with 5.10.0.

    Hm; I was under the impression that the 5.10.1 patchlevel did not restore the performance -- at least all of it -- and assumed the latest patchlevel with each major version in my statement. That is, my statement was '5.10.1 was slow compared to 5.8.9 and 5.12.4 and 5.14.4'

    But please don't mind me -- I may be talking out of my arse.
