Test write and read a file from NFS/SMB/Network Drivers
Create a 200 GB file
dd if=/dev/urandom of=/mylocaldisk/test bs=1M count=200k
Read Locally
dd if=/mylocaldisk/test of=/dev/null bs=1M 214748364800 bytes transferred in 249.877236 secs (859415480 bytes/sec)
Do the same for remote disk mounted
Create a 200 GB file
dd if=/dev/urandom of=/myremotedisk/test bs=1M count=200k
Read remote
dd if=/myremotedisk/test of=/dev/null bs=1M 214748364800 bytes (215 GB) copied, 740,928 s, 290 MB/s
You can use iperf3 to check from NFS/NAS server
