I posted this question to the admin group. I just realized that I
should have sent it here.
I just read the following article:
http://people.planetpostgresql.org/mha/index.php?/archives/162-PostgreSQ
L-vs-64-bit-windows.html
Would there be benefits in running PostgreSQL in a 32 bit mode on a 64
bit version of XP? My thought is that the OS could access more of the
memory for the caching of the files. On my production Linux box, I
don't allocate more than a 2 Gig to PostgreSQL. I leave the rest of the
memory available for the caching of disk files. So even though
PostgreSQL would be running in a 32 bit mode it seems like it would
still run better on a 64 bit XP box compared to a 32 bit version. This
of course assumes that one does have a sizeable database and more than 3
Gig of memory.
Is this a correct assumption?
Would the performance be relatively similar to that of Linux?
Thanks,
