Are we able to have some pause without strict rules like 'stop for 30 sec' ? (case : my hardware is very good and I can write 400MB/sec with no interrupt, XXX IOPS) I wonder if we are not going to have issue with "RAID firmware + BBU + linux scheduler" because we are adding 'unexpected' behavior in the middle. -- Cédric Villemain 2ndQuadrant http://2ndQuadrant.fr/ PostgreSQL : Expertise, Formation et Support -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
