Did a quick check of the current cifs-2.6.git tree (in linux-next, which I will be requesting to be merged into 3.2-pre). Thanks to Jeff Layton's async read patch set, as expected the file copy performance from server to Linux client is dramatically faster. In a quick test copying a directory containing 144MB of movie trailers from a typical Windows Vista desktop system (as desktop) using the Linux cifs kernel client the speed more than doubled. Performance should be even better to Linux/Samba servers due to Samba's larger maximum i/o sizes. When you also consider that Pavel's byte range lock queueing and lock batching patches should help some workloads a lot, and that his SMB2 code will allow oplock (lease) upgrades - the performance of 3.2 cifs kernel client should be much better. -- Thanks, Steve -- 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
