I had a similar problem under Linux where cache hits were really slow on a server that was not busy. Switching to aufs fixed the problem for me (ie just replace the word "diskd" with "aufs" on the cache_dir line). I know the FAQ suggests that diskd gives better performance (or it did the last time I checked). I think that the FAQ may need updating to advise that diskd or aufs may give the best performance depending on the load and OS. Steven
