UKOUG / LOSUG May 2012

Late, but as promised, a quick blog on Dr. Clive King’s presentation to the OpenSolaris User Group in September.

Another great talk which will particularly stick in my mind for the anecdote about the customer who bought larger and larger systems to solve performance problems and ultimately found out that RAM was being artificially limited by a system setting. Ouch. That came from Clive’s tip #1: don’t copy /etc/system settings!

I noted down 10 tips in total and got links to other good blogs like Gerry Haskin’s blog.

By the time the room got hot and stuffy, we were into the realms of chip performance, large pages and MMU traps so we had covered a large spectrum.

If I do any Solaris performance tuning in the future, this talk will certainly be my starting point.
