| |
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
