[Opensim-dev] Trust & distributed grids

Tue Nov 24 17:15:58 UTC 2009

I completelly disagree with:

"MySQL is notoriously not scalable and a load monster"

Then MSSql is not scalable and a superload monster... and Oracle, even
worse...

Which O.S.? Which MySQL configuration? Which hardware configuration?

Personally I have 2 ubuntu server, each one with one mysql instance
(complete server) working in master-slave... and all of this running over
virtual box (installed on windows XP) in the same machine, a 1.75 GHz dual
core with 4 Gb of RAM... and it works smoothly.
