Re: [rules-users] Performance is too bad when using matches predicate

We are considering drool rule engine for data profiling (run the data through the various regex pattern for data analysis) on a large amount of data. We have rules to determine the SSN, Phone number, Driver license number, tracking number etc. Most of our rules are regex pattern matching. I've developed a sample program with 5 rules, all are pattern matching rules and running the rules against million facts/objects (each object has 2 string fields). It takes around 58 seconds versus 2 seconds when I run the same thing with plain JAVA code.
