Novell SLES 10 to OpenSUSE 11.1 Migration

In an effort to save on licensing costs I have just completed the migration from SLES to OpenSUSE. I have to say it was a little unnerving to step away from an enterprise class distribution. There were so many choices when it came to choosing the replacement for SLES, I knew we no longer wished to pay the licensing fee’s to only have access to software updates and support that has never been used (IMHO google for me is the best support agreement).

On the cards were CentOS, Ubuntu LTS, and OpenSUSE. Our main requirements were the ability to access upgrades and the use of an auto build system for rapid deployment. CentOS was ruled out early in the piece (unfortunately I have to say only for petty reasons, none of which are worth listing here). So the competition was between Ubuntu and OpenSUSE, now my personal opinion here would be for Ubuntu to be the successor but unfortunately it had a few fatal flaws.

PostgreSQL Performance Tuning

Well I have had my head buried in Postgres tuning parameters today. There are so many different options to look at and no real definitive guidelines out there, and to make matters worse you can really impede performance with incorrect tuning parameters which is probably counter productive if your interested in tuning for performance :-).

I have read a lot of blog posts and articles today and will list the ones I found most helpful below.
