Very Slow Network Speed

[RobinDP]

Indeed. Issue could be with CPU utilization while running Chromium.

Yeah, CPU load is very high when Chromium is running, which I think is due to hardware acceleration is off. I have another thread for that question.

RPi3 Hardware Acceleration is off

I have followed the instructions from https://www.dedoimedo.com/computers/rpi4-ubuntu-mate-hw-video-acceleration.html but I can only get Okey from cat /proc/device-tree/soc/firmwarekms@7e600000/status and this one shows not found cat /proc/device-tree/v3dbus/v3d@7ec04000/status I can’t get hardware acceleration in Chromium. Please help.
