Re: Quantify small changes to predicate evaluation

Hi Marti,thank you for your quick reply.I tried the proposed tweaks and see
some differences regarding the measurements. It seems as if the overall
query performance dropped a little what I think the disabled turbo boost
mode is responsible for (all measurements are single query only). I think
that kind of behaviour is somewhat expected.Run1: 26.559sRun2:
28.280sUnfortunately the variance between the runs seems to remain high.In
fact I have exclusive access to the machine and I made sure not to run in
any i/o related problems regarding buffer caches.Are there any other
stumbling blocks I'm missing at the moment?Maybe I've to rethink my
(end-to-end) measurement strategy.In your experience how small is it
possible to get measurement variances on Postgres?Thank you very much.Kind
regards,Dennis
