How many indexed tokens does each document have (for the field you are faceting on) on average? How many unique tokens are indexed in that field over the complete index? Or you could go to the admin/stats page and cut-n-paste the fieldValueCache entry after your faceting request - it should contain most of the info to further analyze this. -Yonik http://lucidimagination.com
