Peter,
When we make shadow facts optional we should be able to get another 10%
speed improvements on there, atleast. You can also play around with the
vairous indexes, you may find turning off alpha indexing or left and
right indexing speeds things up. We will also make it possible to turn
off truth maintenance, which should gain a few more percent. I suspect
there may be more performance improvements, maybe a customised result
set for faster access to the results (but less easy to use) - you can
try this yourself by looking at hte QueryTerminalNode and profiling
that. Btw we have free jprofiler licenses for ALL JBoss Rules
contributors, will email you one now.

I 'll have to run it longer to clear away the hotspot effects though,
to get some real good numbers
