Hi everyone on the list. I want to know what is the reccommended OS
to work with PostgreSQL , on specific with PostGIS:
One more question is about what HW (server) offers the best
performance for a Web Map Server bases on PostGIS and mapserver.
In general, you're probably best off running whatever OS you're most
comfortable with.
I'd amend that to say whatever flavor of unix you're most comfortable
with.
Well honestly that isn't true either. Linux is faster then Solaris for
PostgreSQL in a lot of cases. In reality... I would say the best OS for
PostgreSQL is either Linux or FreeBSD. Win32 is great for a small
installation or development.
The Solaris argument may change for 8.2, I don't know.
Many tools aren't quite there on the windows version, and it
still seems to have more issues with performance and scaling than the
unix flavors of PostgreSQL.
No question. The win32 version of PostgreSQL can't go over 300-400
connections depending on the size of your machine without modifying your
registry in a scary fashion.
As for hardware, until recently, AMD was the un-disputed king when it
came to running PostgreSQL (and databases in general). But the newer
Intel CPUs seem to have surpassed the Opteron. I believe there's a
tweakers.net article floating around that did some performance
testing with the new CPUs.
I am still curious about this when you start talking more then say 4
CPUs. AMD IIRC still has the belt for things like memory bandwidth.
I think AMD still has an advantage for CPU >=4 due to the hypertransport
(not cores, actual CPU sockets >=4) Since most loads are easily handled
by two dual core CPUs nowadays, AMD and Intel are about even.
Heh, see above ;)
Much more important is your disk subsystem. Using an Areca RAID
controller with battery backed cache and a half dozen or more hard
drives is often the real winner for performance.
Yes, LSI and 3Ware are also good. I am particularly fond of LSI but
Areca has PCI-Express cards which means you can put them on cheaper
motherboards :)
