Hi, We have developed an application using PG 6.5.1, DBI-1.13 and DBD-0.92 with perl5. We have a small db with a query with 5 joins and other smaller singleton selects. Now this query will be executed about 50 times a second. While doing a load test to find performance we find that for 100 parallel perl requests only around 10 postgres processes get executed. Why is this so. Is there anyway to configure and increase this. -N and -B parameters in postmaster don't seem to help. Thanks in Advance, Murali Differentiated Software Solutions ____________________________________________________________________________ K.P.Krishnan Phones:+91-44-4349882 Client Understanding +91-44-4349469 Intercept Consulting India (P) Ltd Fax: +91-44-4349842 Chennai Mobile 9841064540 India email: [EMAIL PROTECTED] ____________________________________________________________________________ ************
