Hello everyone.


I’m having problems with the performance of queries with  facets, the temp
expend to resolve a query is very high.



The index has 10Millions of documents, each one with 100 fields.

The server has 8 cores and 56 Gb of ram, running with jetty with this
memory configuration: -Xms24096m -Xmx44576m



When I do a query, with 20 facets, the time expended is 4 – 5 seconds. If
the same request is did another time, the



Debug query first execution:

<double name="time">6037.0</double><lst name="query"><double
name="time">265.0</double></lst><lst name="facet"><double
name="time">5772.0</double></lst>



Debug query seconds executions:

<double name="time">6037.0</double><lst name="query"><double
name="time">1.0</double></lst><lst name="facet"><double
name="time">4872.0</double></lst>





What can I do? Why the facets are not cached?





Thank you, Marcos
