[PERFORM] compiling 7.4.1 on Solaris 9
can anyone tell me what the best way to compile postgresql 7.4.1 on Solaris 9 (UltraSparcIII) is? I have latest gmake and gcc installed. I was going to use CFLAGS="-O2 -fast -mcpu=ultrasparc" based on snippets I've read about the place. Would using -O3 be an improvement? thanks ---(end of broadcast)--- TIP 6: Have you searched our list archives? http://archives.postgresql.org

In my experience, it's not only not an improvement, it sometimes breaks the code. That's on 8, though, not 9.

I was wondering if there had been any resolution and if the defaults for 7.4 are considered Ok. thanks ---(end of broadcast)--- TIP 9: the planner will ignore your desire to choose an index scan if your joining column's datatypes do not match

At work, we have been doing a number of tests on 7.4. The performance is such an improvement over 7.2 that the QA folks thought there must be something wrong. So I suppose the defaults are ok.

Previously it wasn't using any optimization flags. -- Jeff Trout <[EMAIL PROTECTED]> http://www.jefftrout.com/ http://www.stuarthamm.net/ ---(end of broadcast)--- TIP 9: the planner will ignore your desire to choose an index scan if your joining column's datatypes do not match

I just wanted to note that we _were_ using optimisation with 7.2. 7.4 is still a lot faster. A -- Andrew Sullivan | [EMAIL PROTECTED] ---(end of broadcast)--- TIP 4: Don't 'kill -9' the postmaster
