Thanks for the feedback, glad it's working out faster for you. Btw have
you tried our sequentail mode, thats even faster, especially for large
data sets and where as JRule's sequential/fastpath modes limit the rule
langauge available to you, we still allow you access to the full
language. Also notice how we don't need to pool rule contexts like
JRules, our single rulebase can be shared amount working memory
sessions, making the management of sessions very light weight which
simplifies your over all infrastructure.<br>
<br>
On the increasing times, that doesn't look good. Probably a bad loop or
cache somewhere. Could you make a self contained project showing this
behaviour and upload it as a jira, and we will track and hopefully move
the bottlebeck. Hopefully JProfiler can shed some light.<br>
<br>
Btw what do you mean by "non-optimized test rule set and data" - just
trying to understand so I can compare apples to apples.<br>
