Hi, DB : POSTGRES 8.4.8 OS : Debian HD : SAS 10k rpm
Shared_buffer is 4096 25 % of RAM , effective_cache is 8GB 75% of RAM After insert trigger is again calling 2 more trigger and insert record in another table depends on condition. with all trigger enable there are 8 insert and 32 updates(approx. update is depends on hierarchy) Plz explain multiple connections. Current scenario application server is sending all requests. -- Thanks & regards, JENISH VYAS On Mon, Jun 27, 2011 at 5:37 PM, Kevin Grittner <kevin.gritt...@wicourts.gov > wrote: > Jenish <jenishv...@gmail.com> wrote: > > > I am using postgres 8.4.x > > With x being what?
