Partitioning the data "tables" is a pain in the butt. It would be nicer if the partitioning is transparent to the application. .. > True.

But these don't scale out. You could look into Terracotta, but it only scales out to TWO boxes. The only solutions I know of which scale out well, and do not require application-level data partitioning, are Coherence and IBM ObjectGrid. Coherence is the simpler solution (two JAR's totalling 10MB only!) and it works with J2SE, does not require J2EE. .. > > Is it really that bad?

I was comparing (whatever the compiler is on FC6) with Windows. And the Windows version of the app is really twice the speed (on a Core processor). _________________________________________________ Philippine Linux Users' Group (PLUG) Mailing List [email protected] (#PLUG @ irc.free.net.ph) Read the Guidelines: http://linux.org.ph/lists Searchable Archives: http://archives.free.net.ph
