Poor Performance during Matching

[Former Member]

Hi Folks,

Total number of records = 700,000

We are trying to find duplicates through the matching process.

When we use matching strategies without transformations - performance is faster .

We would like to use transformations but when we do.. the server seems to just process for ever !!

What are the ways we can improve on the server side - memory/CPU or other config to improve performance during matching using transformations. ?

Hi Vinay,

Try lesserning the transformation used by making use more effective strategies using combinations of different Rules.

Also use the Token Equals property in the Rules tab to identify the seperated tokens as duplicates by making comparison between the token sof the words during the Matching.

This will probabaly reduce the CPU usage nad make the process faster.

When using transformations the Words are actually transformed virtually and then compared so it consumes more time and hence more time.

To know more on the MDM configurations to improve performance you can go through the below links

Hope It Helped,

Vinay,

Transformations are performance-intensive when you play around wt large number of recs.

Matching performed asynchronously.

Multiple CPUs do not help improve the performance of a single matching task(work on your matching strategy - not having to many rules in an strategy), but can help support more concurrent matching tasks (1 CPU for each 1 matching task).

thanks
