Hi Thomas,<br><br>did you already give a look to the release notes of the last 5.3.0.CR1 ?<br><br><a href="http://docs.jboss.org/drools/release/5.3.0.CR1/droolsjbpm-introduction-docs/html_single/index.html#d0e47">http://docs.jboss.org/drools/release/5.3.0.CR1/droolsjbpm-introduction-docs/html_single/index.html#d0e47</a><br>
<br>I personally worked to some optimization of both the MVEL library and Drools internals and, as you can read there, this last release should should be (accordingly to my benchmarks) about 3 times faster in both the supported dialects.<br>
<br>Would be great if you could give it a try and confirm that you experience a similar improvement.<br><br>Thanks,<br>Mario<br>
