Обсуждение: postgresql under Windows is slow
Hi,
anybody has an experience how is stable postgresql under Windows system ?
I tried postgresq 7.1 under Cygwin, Windows 98 and was dissapointed
by very bad performance. Are there something I could tune ?
I got 250 sel/sec on simple select from table with 500 rows !
Under Linux I have 2500 sel/sec.
Regards,
Oleg

Never tried it myself, but I distinctly recall someone reporting that
they got comparable performance on Cygwin as on Linux. You might try
asking on pgsql-cygwin.

As you might guess, Cygwin's speed depends heavily on the version of Windows you are using and its filesystem. I've heard W2k/NTFS gives best performance for apps (like pgsql) that require a lot of disk access. __________________________________________________ Do You Yahoo!?

Try using NT. I use 98 for development but it just drops the ball to much for me to consider it for production (I've never had the regression tests complete on 98, mind you I havn't tried particularly hard either). If there is anyplace I would expect performance difference it would be in connection times due to windows forking (or lack there of).

Just by the nature of the OS, I'd never expect too much performance from a Cygwin app, especially one like postgresql. Do you plan on running it on 98 in a production manner? My own experience is that postgresql runs quite a bit slower on WinMe than my NetBSD box (same hardware), but I don't consider that to be a problem.

It's amazing how entrenched Windows is. > > My own experience is that postgresql runs quite a bit slower on WinMe than > > my NetBSD box (same hardware), but I don't consider that to be a problem. > > > > Did you make some special tuning ? btw, what's about locale support ? It was a very quick, seat of the pants test. I made a junk schema with some insert statements. I noticed that it took a few seconds longer to finish on Windows than in NetBSD. Didn't do anything more than that. Don't know about locale stuff, I never have to change that stuff... Andy acruhl@sdf.lonestar.org SDF Public Access UNIX System - http://sdf.lonestar.org

hug... wakala... I have PostgreSQL running in several boxes, since a clonic PIII400 , two NetVista PIII800 and two NetFinity PIII 550. All of them are Linux boxes, and obviously there are some performance diferences related to the hardware, so I try hack hard to get best performance posible in each case, but I never ever think to use a guindous box to do serious work, especially if it is a guin98. I hope you know that Linux 'n, FreeBSD are free and without costs, so why pay for a cuasi-OS that is going to break your brain and make you live the IT practice ? ? ? Try it on Linux on the half hardware 'n tell us later. Best for you and Greetings
