[rules-users] Jbilling Drools performance

[Antonio Anderson Souza]

Dear Thomas,

My first try was to use the matches and the performance was slower about 3
minutes to process only one CDR, after this benchmark and some research I've
tried to use the per digit comparison.

The order of this table that I sent is inverted, the most general entries
must be analyzed first.

I'm still analyzing how to change JBilling to use per digit comparison to
benchmark the performance of this solution.

Thank you very much for your tips.

Best regards,
