Re: [rules-users] Upgrade to Drools 5 - loss of performance
During a few experiments I did with MVEL, I have found that 2.x
actually performs slower than 1.x in our case. Maybe that is a
starting point.
Scott, do you have the possibility to profile your application using
4.x and using 5.x? That should reveal the bottlenecks and I am sure
that the dev crowd would be glad receiving that input.

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?
Thanks,
Scott
