Обсуждение: Tuning Postgresql on Windows XP Pro 32 bit

All,<br /> Is there a place where I can find information about tuning postgresql running on a Windows XP Pro 32 bit
system?I installed using the binary installer. I am seeing a high page fault delta and total page faults for one of the
postgresqlprocesses. Any help would be great.<br /><br /> Doug Knight<br /> WSI Corp.

We are running the binary distribution, version 8.2.5-1, installed on Windows XP Pro 32 bit with SP2. We typically run
postgreson linux, but have a need to run it under windows as well. Our typical admin tuning for postgresql.conf doesn't
seemto be as applicable for windows.<br /><br /> Doug<br /><br /> On Sun, 2008-01-06 at 18:23 +0500, Usama Dar

So what have you tuned so far? what are your current postgresql settings 
that you have modified? What are your system specs for Hardware, RAM , 
CPU etc?

We tried reducing the memory footprint of the postgres processes, via shared_buffers (from 30000 on Linux to 3000 on Windows), max_fsm_pages (from 2000250 on Linux to 100000 on Windows), max_fsm_relations (from 20000 on Linux to 5000 on Windows), and max_connections (from 222 on Linux to 100 on Windows). Another variable we played with was effective_cache_size  (174000 on Linux, 43700 on Windows). None of these reduced memory usage, or improved performance,  significantly. We still see the high page fault rate too. Other things we tried were reducing the number of WAL buffers, and changing the wal_sync_method to opendata_sync, all with minimal effect. I've attached the latest version of our Windows postgresql.conf file.

Doug,

This thread really should be moved to pgsql-performance mailing list.  Thanks, 
and good luck tuning Windows.
