That is correct, we see similar if not longer query times if run in a regular query through the admin tool using the same terms that MLT is selecting. I was testing MLT to see if this was an unavoidable consequence of having terms that occur in a large number of documents, or whether it was some artifact of how I had the DisMax functionality configured on my other handler.
Am I correct in assuming that the answer to this is "wait for Moore's Law", and that I likely would have been looking at 3-5 second query times a couple of years ago? Eric, from what I can tell from your description, it looks like this could indeed be caused by high frequency of some of the query terms. This is not MLT component specific, and I imagine you will see similar performance if you just run queries with those terms from, say, the Solr admin page.
