Yes, we (Software AG) have a source license, so it'd be great if you could provide a patch for this.

This method will get called when you evaluate the hash code of a Java object in the Rete memory; this will happen often during pattern matching. There's actually enough room to cache the hash code in the members of the Value class that are unused for Java object values, so we could try that as a performance improvement. Do you have a source license, so I could send you a patch to try?

Our implementation uses the Slot Specific feature. Using a Java profiler, HashCodeComputer.isValueObject() stood out as one of the main contributing factors, if not the most likely, to the degradation -------------------------------------------------------------------- To unsubscribe, send the words 'unsubscribe jess-users y...@address.com' in the BODY of a message to majord...@sandia.gov, NOT to the list (use your own address!)
