We do that on a daily basis at State and University Library, Denmark: One of our facet fields has 10766502 unique terms, another has 6636746. This is for 11M documents and it has query response times clustering at ~150ms, ~750ms and ~1500ms (I'll have to look into why it clusters like that). This is with standard Solr faceting on a quad core Xeon L5420 server with SSD. It has 16GB of RAM and runs two search instances, each with ~11M documents, one with a 52GB index, one with 71GB. - Toke Eskildsen
