Hi,
I am about to order a new server for my Postgres cluster. I will
probably get a Dual Xeon Quad Core instead of my current Dual Xeon.
Which OS would you recommend to optimize Postgres behaviour (i/o
access, multithreading, etc) ?
I am hesitating between Fedora Core 6, CentOS and Debian. Can anyone
help with this ?
Well, all three you mention are much the same, just with a different
badge on the box, as far as performance is concerned. They're all
going to be a moderately recent Linux kernel, with your choice
of filesystems, so any choice between them is going to be driven
more by available staff and support or personal preference.
I'd probably go CentOS 5 over Fedora just because Fedora doesn't
get supported for very long - more of an issue with a dedicated
database box with a long lifespan than your typical desktop or
interchangeable webserver.
I might also look at Solaris 10, though. I've yet to play with it
much, but it
seems nice, and I suspect it might manage 8 cores better than current
Linux setups.
Cheers,
Steve
