Rock Pi 4B and Ethernet speed

Recommended Posts

I am observing huge difference in samba speed (both ways to/from PC on Gigabit Ethernet) with Rock Pi 4B. Earlier I had Debian and Ubuntu provided by Radxa and recently speed has gone from 115 MB/s to ~12 MB/s.

I moved to Armbian which is currently available for download. Before any updates I had 115 MB/s transfer speed.

When I updated to Armbian 20.08.11 Focal with Linux 5.8.15-rockchip64 the speed has go down to ~15 MB/s.

 

The bigger change that happened was kernel upgrade.

I exclude problems like: PSU (it is over enough), home network (nothing has changed) and SSD speed (checked - 330 MB/s).

Has anyone else also observed limited speed recently?
