I run a Perl/CGI driven website that makes extensive use of PostgreSQL (7.4.3) for everything from user information to formatting and display of specific sections of the site. The server itself, is a dual processor AMD Opteron 1.4Ghz w/ 2GB Ram and 2 x 120GB hard drives mirrored for redundancy running under FreeBSD 5.2.1 (AMD64).
Recently loads on the site have increased during peak hours to the point of showing considerable loss in performance. This can be observed when connections move from the 120 concurrent connections to PostgreSQL to roughly 175 or more. Essentially, the machine seems to struggle to keep up with continual requests and slows down respectively as resources are tied down.
Have you taken a look at pgpool? I know, it sounds silly to *reduce* the number of DB connections through a connection pool, but it can help.
