I have had a similar experience. Most sites with Anubis take only a few seconds to go through, but I ran into I think it was some small blog where it took at least 5 minutes. Like someone mentioned, it may have been how they set it up with number of hashes required. The site that took forever for me seemed to have some exorbitant number like 5k or 50k (I don’t recall exactly).
