i have update my OMV 4 to OMV 5.
No other changes!
NFS or SMB copy is 2-4 times slower as before with OMV4.
Copy aprox. 2000 files 45 MB to the OMV takes 12 minutes
Copy aprox. 2000 files 45 MB from the OMV takes 4 minutes
Copy of one single file with 256 MB from/to OMV takes 5 seconds. ( Strange! )
iperf Bandwidth aprox. 900 Mbits/sec
The same copy operation to my other NAS takes 4 minutes.
The same copy operation from my other NAS takes 30 seconds.
My other NAS was slower as my old OMV4.
The only way is back to OMV4 but i don't wanna use an old system.
