Performance of Pavel's multicredit i/o SMB3 patches continues to look good. Additional informal performance results below comparing cifs mounts with smb3 mounts (vers=3.0) with and without Pavel's patch set. I plan to do additional testing with large rsize/wsize (default with Pavel's code is 1MB). 3.16-rc4 (Ubuntu) on client. Server is Windows 8.1. Both VMs on same host (host disk is fairly fast SSD). Copy to server performance increased about 20% percent dd if=/dev/zero of=/mnt/targetfile bs=80M count=25 got similar results with or without conv=fdatasync 1st run copying to empty directory, 2nd run copying over targetfile, (pattern repeated multiple times) averaging results New code (with Pavel's patches) --------------------------------------------- CIFS 167MB/s SMB3 200MB/s Existing code (without his patches) ------------------------------------------------ SMB3 166MB/s CIFS 164.5MB/s For large file reading SMB3 performance with Pavel's patches increased 76% over existing SMB3 code dd of=/dev/null if=/mnt/targetfile bs=80M count=25 (mounting and unmounting between attempts to avoid caching effects on the client) New code (with Pavel's patches) --------------------------------------------- CIFS 114MB/s SMB3 216MB/s Existing code (without his patches) ------------------------------------------------ SMB3 123MB/s CIFS 110MB/s -- 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
