[GeoNetwork-devel] Challenges of Geonetwork CSW performance for concurrent requests

[Kai L. <kl...@gm...>]

Hi all,
We set up a clearinghouse based on GeoNetwork opensource2.4.3 ( http://clearinghouse.cisc.gmu.edu/geonetwork ). About 26K records have been ingested into the clearinghouse. 

When 1 CSW request was sent to the clearinghouse, the time to get the response is 2.6 seconds. 

Now I test the performance when 100 CSW requests are sent to the clearinghouse concurrently and get the average is 83 seconds. 

The average response time (83s) is much longer than sending only 1 request. Is it normal? 
Thanks,
