Unfortunately, we're somewhat hamstrung by the protocol when talking to standard cifs servers, so there's not a lot we can do to make it go faster. Depending on the number of concurrent requests that the server will allow, you may be able to get the speed up even more. Once Steve does his promised patch to make the client respect the MaxRequests value that the server sends during the protocol negotiation, that may increase the concurrency and hence the throughput. -- Jeff Layton <jlayton@xxxxxxxxx> -- To unsubscribe from this list: send the line "unsubscribe linux-cifs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
