>  Issue Type: Bug
>  Security Level: Public(Default Security Level. Issues are Public) 
>  Components: Facet Module
>Affects Versions: 7.5

> The FacetFieldProcessorByHashDV constructor is currently calling:
> {noformat}
> FieldInfo fieldInfo = 
> fcontext.searcher.getSlowAtomicReader().getFieldInfos().fieldInfo(sf.getName());
> {noformat}
> Which is reconstructing FieldInfos each time.  Simply switching it to:
> {noformat}
> FieldInfo fieldInfo = 
> fcontext.searcher.getFieldInfos().fieldInfo(sf.getName());
> {noformat}
>  
> causes it to use the cached version of FieldInfos in the SolrIndexSearcher.
> On my index the FacetFieldProcessorByHashDV is 2-3 times slower than the 
> legacy facets without this fix.
