I have updated the Solaris FAQ: 5) How can I compile for optimum performance? Try using the "-fast" compile flag. The binaries might not be portable to other Solaris systems, and you might need to compile everything that links to PostgreSQL with "-fast", but PostgreSQL will run significantly faster, 50% faster on some tests. -- Bruce Momjian | http://candle.pha.pa.us [EMAIL PROTECTED] | (610) 359-1001 + If your life is a hard drive, | 13 Roberts Road + Christ can be your backup. | Newtown Square, Pennsylvania 19073 ---------------------------(end of broadcast)--------------------------- TIP 5: Have you checked our extensive FAQ? http://www.postgresql.org/docs/faqs/FAQ.html
