Re: [PERFORM] Suggestions for benchmarking 7.4RC2 against 7.3
RC2 is running in production without any apparent problems till now. Well its difficult to say at the moment how much speed gain is there unless the heavy duty batch SQL scripts are run by cron. Count(*) and group by on large tables are significantly (5x) faster and better error reporting has made it easier to spot the faulty data. eg in fkey violation. Will post the OSDB .15 versions' results on 7.3 & 7.4 soon. Regds Mallah.

That's a much more respected database test, and probably less buggy than OSDB. Hmm... really sorry! my pg_dump | psql is almost finishing in next 20 mins. creating indexes at the moment :) Really sorry can't rollback and delay anymore becoz my website is *unavailable* for past 30 mins. I ran OSDB .15 version and pg_bench . Regds Mallah.
