Overview

A number of performance issues have been found when GN is applied to catalogs containing 10s of thousands of records:

• search speed: search speed appears to degrade badly with the size of the result set, ie. searches with large result sets were taking much longer than expected to process than searches with small result sets
• indexing speed: importing 10s of thousands of records via batch import, harvesters, massive operations and CSW transactions was taking too long eg. local file system harvest of 20k records was taking 10-12 hours...
