[rules-users] Memory Control

[Wolfgang Laun]

Experet and Fusion are the same Engine. The difference you are
reporting is bound to be due to different Event types and different
rules.

There are several possibilities why things slow down. Have you
analysed your application's behaviour using the usual monitors, e.g.,
to learn about GC frequency?

Do you need to keep 300K or 500K facts in WM?
