Dear All,
I've finished the tests with the digit per digit comparison without eval,
but the performance does not increased a lot, it still taking about 1 minute
per CDR, that is so slow for a Telecom Carrier, follow a piece of the new
spreadsheet below:

Do i need to make some special treatment to get Drools indexing my rules?
I'm using the guvnor to upload the spreadsheet and compile the rules.
Does anybody have some tips to increase the performance?
Thank you very much,
