Only when we have major projects committed can we move towards measuring things and correcting deficiencies. Doing tuning last is a natural consequence of the first rule of tuning: Don't. That means we have to wait and see what problems emerge and then fix them, so there has to be a time period when this is allowed. This is exactly the same on any commercial implementation project - you do tuning at the end before release. I fully accept that this is not a time for heavy lifting. But it is a time when we can apply a few low-invasive patches to improve things. Tweaking the bgwriter is not exactly a big or complex thing. We will be making many other small tweaks and fixes for months yet, so lets just regard tuning as performance bug fixing and get on with it, please. -- Simon Riggs http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Training & Services -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
