As I understand it, you changed from single to multi shard. Guessing wildly: You have one or more facets with a non-trivial (10K or more) number of unique String values and you have a fairly high facet.limit (50+). If so, what you see might be the penalty for the two-phase faceting with SolrCloud, where the second fine-counting phase can be markedly slower than the first. There are ways to help with that, but let's hear if my guess is correct first. - Toke Eskildsen
