Hi Heikki Linnakangas, Thanks for yoru kind response. We were looking on how to improve the performance of our application which is using PostgreSQL as backend. If postgreSQL is supporting data page caching in the shared memory then we wanted to design our application to read/write using the shared memory rather than accessing the DB everytime so that, it will improve the performance of our system. If this is possible can you please tell us how can we implement the same. Any idea on the same is of very much help. Thanks in Advance, Ramachandra B.S. -----Original Message----- From: Heikki Linnakangas [mailto:hlinnaka@xxxxxxxxx] On Behalf Of Heikki Linnakangas Sent: Tuesday, January 16, 2007 3:04 PM To: Ramachandra Bhaskaram (WT01 - IP-Multimedia Carrier & Ent Networks) Cc: pgsql-performance@xxxxxxxxxxxxxx Subject: Re: [PERFORM] Caching in PostgreSQL ramachandra.bhaskaram@xxxxxxxxx wrote: > > Hi, > > Can anybody tell me how can I implement data Caching in the shared > memory using PostgreSQL. PostgreSQL, like most other DBMS, caches data pages in shared memory. What exactly are you trying to accomplish?
