Yeah. This patch in the current state is likely much much slower than
unpatched master, except in extreme cases where you have thousands of
connections and short transactions so that without the patch, you spend
most of the time acquiring snapshots.
What else are you looking to accomplish with this patch during this
'fest? Bug finding? Design review? Performance testing?
Design review, mostly. I know the performance still sucks. Although if
you can foresee some performance problems, aside from the extra CSNLOG
lookups, it would be good to know.
I think for this commitfest, I've gotten as much review of this patch
that I can hope for. Marking as "Returned with Feedback". But of course,
feel free to continue reviewing and commenting ;-).
