Which plattform do you recommend I run PostgreSQL for best performance?

Hello I am doing a comparison between MySQL and PostgreSQL. In the MySQL manual it says that MySQL performs best with Linux 2.4 with ReiserFS on x86. Can anyone official, or in the know, give similar information regarding PostgreSQL? Also, any links to benchmarking tests available on the internet between MySQL and PostgreSQL would be appreciated. Thank you! Tim

I can tell you that any *NIX variant on any modern hardware platform will give you good performance, except for Cygwin/x86. Any differences between OSes on the same hardware are completely swamped by far more direct concerns like IO systems, database design, OS tuning etc. Pick the OS you're most familiar with is usually a good recommendation (and not just for Postgres).

Don't know which OS/filesystem PostgreSQL runs best on, but you should test on whatever OS and filesystem you are most experienced. Whatever speed gain you may get from "best setups" will mean little if the machine crashes and you don't know how to fix it and get it back up quickly.

PostgreSQL runs on a lot more platforms than MySQL; it's not even reasonable to compare some of them, like rtLinux, AIX or Cygwin. The only reasonable comparative testing that's been done seems to indicate that: Linux 2.6 is more efficient than FreeBSD which is more efficient than Linux 2.4 all of which are significantly more efficient than Solaris, and ReiserFS, XFS and JFS *seem* to outperform other Linux journalling FSes. However, as others have said, configuration and hardware will probably make more difference than your choice of OS except in extreme cases. And all of the above is being further tested, particularly the filesystems. -- --Josh Josh Berkus Aglio Database Solutions San Francisco

Can anyone official, or in the know, give similar > information regarding PostgreSQL? The fastest I have ever seen PostgreSQL run is on an IBM pSeries 650 system using AIX 5.1 and JFS2. There aren't many Linux systems that are anywhere _near_ as fast as that. There's some indication that FreeBSD 4.9, running the Berkeley FFS filesystem might be the quickest way of utilizing pedestrian IA-32 hardware, although it is _much_ more important to have a system for which you have a competent sysadmin than it is to have some "tweaked-out" OS configuration. In practice, competent people generally prefer to have systems that hum along nicely as opposed to systems that have ben "tweaked out" such that any little change will cause them to cave in. Benchmarks are useful in determining: a) Whether or not it is realistic to attempt a project, and b) Whether or not you have made conspicuous errors in configuring your systems. They are notoriously BAD as predictive tools, as the benchmarks sponsored by vendors get tweaked to make the vendors' products look good, as opposed to being written to be useful for prediction. See if you see anything useful from MySQL in this regard: <http://www.mysql.com/it-resources/benchmarks/> > Also, any links to benchmarking tests available on the internet > between MySQL and PostgreSQL would be appreciated. Most database vendors have licenses that specifically forbid publishing benchmarks. -- (reverse (concatenate 'string "gro.mca" "@" "enworbbc")) http://www3.sympatico.ca/cbbrowne/oses.html Do you know where your towel is?
