Hi

what are the steps to improve performance and what can be tuned to improve performence in match stage?

Step 1 is to define what you mean by performance.

Step 2 depends on where you are getting your data from. For example, doing a GeoMatch where one of the sources is a database table you can create extra columns for the standardized forms in that table, and index them.

greetings,

I am using falt file to flat file geomultiple duplicate match. Is there any tuning in qualitystage to improve performence faster>

Not really, if the sources are flat files. Adding more memory might help, if system monitoring shows heavy paging/swapping activity. QualityStage itself has no controls that you can tweak.

A final thought; are you processing any unnecessary data? If so, remove this early in the processing stream.
