FTP uploads slower to shared NetApp drive device than to the physical server
Posted on 2012-03-19
Transfers to VM to NetApp \\servername\share slower than transfers to the \\physicalserver\share. About 50% slower.
My storage hosting company describing this as current CIFS shares use backend SATA disk, while the VMDK datastores use the higher speed SAS disks. Also you add in the overhead of CIFS protocol and the fact it has to still be copied to the VM (memory), then to the NetApp share. This adds some latency.
I just don't see how is it related to CIFS shares or disks could be so much different. Any advice?
