Re: [rules-users] Drools Fusion Performance Evaluation
The standard well-established answer to this kind of question is that no
benchmark can provide a reliable basis for predicting the behaviour of any
particular application.
It's easy to benchmark the simple insertion of facts (= events) where there
is no or just a single rule; this will give you an upper threshold for
#/sec. But then it depends on the number and complexity of your rules; the
(average) number of activations that have to be created; how long firings
take; what has to be done in the WM; etc., etc.
Event processing is not different from plain fact processing - it's the very
same engine. Temporal operators are bound to be a little slower than plain
comparison operators.

Hi all!****
** **
Can anybody point me to a performance evaluation of Drools? I found some
papers [1], [2] which focus on the rules part but I’m particularly
interested in the event processing part of Drools. I want to know how many
events can be processed per second with which latency, something that is
similar to the performance evaluation of Esper [3].****
