This might be an explanation for the great drop in performance in case of tests done with checksumming enabled. (BTW, I always stated that we have 1.6.4.1 on servers, but nobody had mentioned so far that there might be a problem on that side...) I however worry much more about the case when checksumming is disabled. Do you think that the 20% performance drop may also be explained by the combination of (1.6.4.1 server / 1.6.5.1 client)??
