I am faceting on the single values only. I ran load test against solr app and found that under increased load the faceting just gets slower and slower. That is why I wanted to investigate filtercache and any other features to tweak the performance. As suggested by Mark in the earlier email, I increased the size of filtercache and the performance has improved. I need to further test to see the impact on other areas.

I was wondering how the heck the filterCache played into counting off a FieldCache. -- - Mark http://www.lucidimagination.com
