Yes, setting CIFSMaxBufSize=65535 produced a jump from ~40-50mb/s to 70-80mb/s when doing dd or rsync -W copies to a CIFS mounted share. Setting it to the maximum worked fine too, but I've only tested with Samba on Linux - I don't know what the performance implication would be with a Windows client.
GVFS defaults the window size to 65535 (well, 65534 due to an issue they found there somehow) though it has other performance issues but it may explain reports of CIFS mounts being a lot slower then GVFS for some people. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1236607 Title: cifs.ko should default to CIFSMaxBufSize=65535 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1236607/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
