[gpfsug-discuss] SMB access speed

[Yaron Daniel]

Hi

It could be that GUI use in the "background" default command which use smb 
v1.

Regard copy files from GPFS to Local HDD, it might be related to the local 
HDD settings.
What is the speed transfer between the local HHD ? Cache Settings and so..

 
Regards

Many thanks Yaron, after the change to disable encryption we were able to 
increase the speed via Ubuntu of copying files from the local desktop to 
our gpfs filestore with average speeds of 60Mbps.
 
We also tried changing the mount from vers=3.0 to vers=2.1, which gave 
similar figures
 
However, using the Ubuntu gui ( Unity ) the speed drops down to 7Mbps, 
however, we?re not concerned as the user will use rsync / cp. 
 
The other issue is copying data from gpfs filestore to the local HDD, 
which resulted in 4Mbps.
