NAS: TVS-1282T3
QTS: 4.3.5.0728
Client OS: Ubuntu 20.04
Client HW: 2 x Xeon E5-2650 v1 - 128GB RAM
Protocol: NFS
Mounting through "/etc/fstab":
10.10.10.3:/NASFolder/ /mnt/NASFolder nfs async,_netdev 0 1
Mounting manually:
mount.nfs 10.10.10.3:/NASFolder /mnt/NASFolder -o async
* Both mounting ways gave the same results.
Testing scenario:
Copying from/to RAM-Drive (50GB) in Client machine to/from NAS Folder mounted on /mnt/NASFolder.
Testing file: A) 43 GB and B) 18 GB
Copying from NAS to RAM-Drive: 500 MB/sec
Copying from RAM-Drive to NAS: 1.0 GB/sec
Copying from NAS to NAS: 350 MB/sec
Copying from RAM-Drive to RAM-Drive: 1.8 GB/sec
I cleared caches prior to every single copy test.
NAS reads are half (or less than half) of the speed of writes. This doesn't sound neither good nor normal.
Am I missing something? Any idea about this phenomenon?
Regards,
Reads are 50% of the speed of writes.
