Definitely. Which workloads are you thinking of? I can think of those affected facets: snapshot speed, commit speed with writes, connection establishment, prepared transaction speed. All in the small and large connection count cases. I did measurements on all of those but prepared xacts, fwiw. That definitely needs to be measured, due to the locking changes around procarrayaddd/remove. I don't think regressions besides perhaps 2pc are likely - there's nothing really getting more expensive but procarray add/remove. Andres Regards, Andres -- Sent from my Android device with K-9 Mail.
