title: Looking for ways to make Drools / Optaplanner faster
body: <p>I am working on a capstone project using    <code>Optaplanner 6.2.0.CR4</code>    and <code>Drools</code> to incrementally score the solution. The problem is pretty similar to <code>Optaplanner's Nurse Rostering example</code>, with a little added complexity. I was wondering if there were any common pitfalls that can slow down Drools that I could look for in my code. The solver runs the <code>Construction Phase</code> pretty quickly, but hits a wall when it gets to the <code>local search phase</code>. Drools is inserting a lot of additional stuff like counting work days per pay period, blocks of specific duration free time per pay period, etc and I'm thinking the way I wrote the rules might be the problem.</p>
