RPI3 update and slow samba performance



i have different share mounted on my RPI with one of this being a samba share mounted by FSTAB

// /home/osmc/USB_DISK cifs _netdev,credentials=/home/osmc/rt2600_smb_perm,nosetuids,noperm,nofail,rw 0 0

no issue for years, then updated to latest OSMC and performance is now terrible at the point i can’t stream files anymore.
The samba share perform fine if connection if from other devices so it is definitely RPI + OSMC.

No idea what could be the issue though.
I also recently upgraded (few month before OSMC upgrade) from RPI2 to RPI3 just transferring SD: not sure if this could have caused some issue but, before OSMC upgrade, as said all was fine.

Hope someone can help!


Check your network throughput with iperf3


ok it seems there is an issue as network is running at 10Mbit:

[ ID] Interval           Transfer     Bitrate
[  5]   0.00-10.09  sec  10.7 MBytes  8.87 Mbits/sec                  receiver

on another RPI3 running HASSBIAN i get:

[ ID] Interval           Transfer     Bitrate
[  5]   0.00-10.05  sec   329 MBytes   275 Mbits/sec                  receiver

which is fine.
It looks like issue is on OSMC?

also i get:

sudo ethtool eth0 | grep Speed
Speed: 100Mb/s


ok found the issue and looks like is not OSMC: reboot my router (synology MR2600AC wired in mesh configuration to Synology RT2600AC) and now looks fine with 100Mbit/s speed
