Thank god, no. ASCII is so 1995...
:)
However, if you can, please post the code, so that we can run benchmarks
ourselves, and figure out what the difference is exactly and whether one
can do something about it.
Unfortunately the code is large and complicated - although I'm prepared to
find and create
test cases and post those.
5.8.x fixes quite a few bugs of 5.6, and in somecases these fixes make the
code slower (due to more checks/conditions).
Indeed - the reason why I'm upgrading to 5.8.x is because of bug fixes - was
just a shock to see such a drop in performance.
Cheers,
