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,

So are you counting only the top level inserts or also the ones
generated by the recursive inserts?

First you need to find out what the bottleneck is.

To achieve parallel processing in PostgreSQL you need to use
multiple connections.
