Unfortunately, after the upstream fix, the performance penalty is still
2-4x.  Prior to the fix, it was 8-12x.  Relative benchmarks including
5.8.8-24 were posted in
http://lists.scsys.co.uk/pipermail/dbix-class/2007-October/005119.html

The latest RH package I have tried is 5.8.8-31, which still has the same
problems.
