Red Hat Bugzilla – Bug 1284870
(RHEL7) Poor performance of sequential/streaming I/O over SMB
Last modified: 2016-03-01 01:09:38 EST
Description of problem:
Streaming read / write workloads perform poorly with Samba/SMB on top of Gluster, when compared to NFS or native client. On the other hand, on local file systems, SMB is fast.
More details to follow.
71% perf improvement on writes and 100% improvement on reads, verified.
Note that with Linux clients we SHOULD NOT be using AIO, there are issues with the cifs kernel module that need to be addressed before we recommend AIO with linux cifs. AIO is recommended for Windows and is enabled by default.
looks good to me. Thanks!
