Hello Andres, >> I'm not sure I've seen these performance... If you have hard evidence, >> please feel free to share it. > > Man, are you intentionally trying to be hard to work with? Sorry, I do not understand this remark. You were refering to some latency measures in your answer, and I was just stating that I was interested in seeing these figures which were used to justify your choice to keep a shared writeback context. I did not intend this wish to be an issue, I was expressing an interest. > To quote the email you responded to: > >> My current plan is to commit this with the current behaviour (as in >> this week[end]), and then do some actual benchmarking on this specific >> part. It's imo a relatively minor detail. Good. From the evidence in the thread, I would have given the per tablespace context the preference, but this is just a personal opinion and I agree that it can work the other way around. I look forward to see these benchmarks later on, when you have them. So all is well, and hopefully will be even better later on. -- Fabien.
