Hi,
I'm using Odroid HC1 for quite a long time and I've observed much degradation on SMB/NFS speed when making upgrades to the board. I'm not sure why? Maybe I'll find some idea what it can be.
Previously the board was working with speeds >100MB/s when reading from it on Windows (smb) or Linux (nfs) now max speeds on the same configuration are ~40 MB/s. That's way too slow. I don't see any process to hang on pc, while copying using smb the samba process is using not so big amount of CPU on big cores from what I see.
I've grabbed armbianmonitor output so you can check it also: http://ix.io/1zrL Currently I'm working on: 4.14.87-odroidxu4
Thanks,
Marcin
