Re: [GeoNetwork-users] performance of GeoNetwork ?

[Jeroen T. <Jer...@fa...>]

Hi Jean Francois,
GeoNetwork uses Lucene indexes for searching and presenting results. =20
This does not require connecting to the database, and therefor the =20
search performance depends on the speed of the Lucene indexes. Lucene =20=

is known to handle millions of records, you should be able to find =20
tests on the web that analyze its performance.
Only when presenting full metadata will GeoNetwork retrieve the =20
record from the DB.
Hope this helps, ciao,
Jeroen
