Re: [rules-users] Upgrade to Drools 5 - loss of performance

I just upgraded our app from Drools 4 to 5 libraries. We just use the
rules engine with DRL. The performance of the engine on our rulebase
is unacceptably slow. I assume there is something we need to do to
our rules or the way we are configuring the engine to fix this. I
don't see anything in the release notes about backwards compatibility
issues. I would very much appreciate it if someone would direct me to
any documentation that explains what needs to be done so our 4.0 rules
perform at least as well as they did before the upgrade?
sigh.... This is why we
need people to get involved prior to a final
release, so we can make sure we've done all necessary tuning for our
user base. We have other users, who did get involved in this, saying we
are faster for their use case. There are some use cases where 5 is
slower, but it should be marginally slow, but it's scalability should be
better for more facts and facts with larger number of fields.
Could you produce a self contained project, with a unit test, that
demonstrates this unnacceptable behaviour?
