Yes, that's normal for a single node connected to a single client testing a single threaded operation. Once you start scaling up to many nodes and test under many read/write threads, the FUSE client ends up being a lot faster. As such, choose how you mount up your shares based on your workflow. -Dan On 25 October 2013 19:01, Jung Young Seok <jung.youngseok at gmail.com> wrote: > > Dear GlusterFS Engineer, > > I have questions that my glusterfs server and fuse client > perform properly on below specification. > > It can write only 65MB/s through FUSE client to 1 glusterfs server (1 brick > and no replica for 1 volume ) > - NW bandwidth are enough for now.
