Thanks! -- George Mitchell > There's a weird (and you need to have a weird sense of humour to enjoy it) flick called "Stranger than Paradise". Anyhow, the above sounds like good news, although the commit it was related to should have had no effect on perf, from what I can see. Assuming that you are using the regular 8.n client (and not the new one), there have been some commits related to krpc bugs that could have fixed cases which would have caused poor perf., although all of those (except one where a client would hang on a TCP reconnect attempt) are in 8.2. So, happy to hear it works for you now, but have no idea why;-) rick
