What I'm saying, and I'm not alone in this, is that setting it higher can actually decrease performance for various reasons. Setting it to 25% of memory on a system with 512GB of RAM for instance, would be tantamount to disaster. A checkpoint with a setting that high could overwhelm pretty much any disk controller and end up completely ruining DB performance. And that's just *one* of the drawbacks. > > > > ______________________________________________ > > See http://www.peak6.com/email_disclaimer/ for terms and conditions related to this email > > > -- > Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) > To make changes to your subscription: > http://www.postgresql.org/mailpref/pgsql-performance > Ok. Just need to know what think another developers about this - should pgtune care about this case? Because I am not sure, what users with 512GB will use pgtune. -- Alexey Vasiliev -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
