yes if you understand the rete diagram you can can help it with understanding performance. If you click on a node it tells you the type. Which are roughly
root, object type node, alpha node, join node, not node, exists node, eval node and terminal node. Can't remenber which has which colour, but you should be able to figure it out, we discuss the node types briefly in the manual.

Hi,

I was trying to make some sense out of Rete Diagram for my rules (DROOLS 3.1M), and one of the questions I have is what all these colors mean? There are red, blue, yellow, green, orange, white, cyan and black circles…. I might be wrong, but I think this should mean something!

Also, I noticed that by default the diagram is displayed in ‘layers’ of dots. In my case I have 7 layers, the top one being the ‘root’ I assume (single white circle). The ‘widest’ layer is the middle one – the forth layer. So, generally the diagram has a diamond shape. I wonder if one can use this kind of visual information to make a rough estimation/assumption on how efficient his rules/constraints are, some hints into optimization, etc….

Thanks,

Vlad
