For any library Benchmarking is very much required in terms of evaluating the performance and helps us to improve the performance better.
I have benchmarked two things:
- Loading 100 and 1000 rules into KnowledgeBase
- Executing a fact against rules against 100 and 1000 rules
All the tests will run for multiple times to see how it is performing by changing the value of N
N is b.N where b is an instance of *testing.B

To execute a fact against 100 rules, Grule Engine took ~9697 ns/op (took the highest value as base) that is hardly ~0.009697ms and 3957 B/op which is pretty fast.
To execute a fact against 1000 rules, Grule Engine took ~568959 ns/op (took the highest value as base) that is hardly ~0.568959ms and 293710 B/op which is also pretty fast.
