Hi, Solr Developers

 

       We are blocked by solr facet performance when query hits many documents. (about 10,000,000)

 

Details as follow:

       I have single solr node (solr version is 4.6 ), total has 320,000,000 documents( local index is about 30G)

 

the index directory as follow


The cache configure as this:

<filterCache class="solr.FastLRUCache"

                 size="1024000"

                initialSize="1024000"

                 autowarmCount="102400"/>

 

<queryResultCache class="solr.LRUCache"

                     size="1024000"

                     initialSize="1024000"

                     autowarmCount="102400"/>

 

<documentCache class="solr.LRUCache"

                  size="30720"

                   initialSize="30720"

                   autowarmCount="3072"/>

 

 

When we query the field eg. default_search: type or default_search: retail,

in the response , numfound is about one million and hits cache QTime is <int name="QTime">2</int> OR <int name="QTime">1</int>.

 

But when we add several facet.field to do facet , QTime  increase to 220ms or more.

 

We add the parameter facet.threads=20, but the improvement is not obvious, and unstable.

 

Do you have some advice on how improve the facet performance when hit many documents.

Alice Yang
