I google it and someone told to add smsc95xx.turbo_mode=N to /boot/cmdline.txt

@sam_nazarko Is this ok? Or is it another issue?

my config.txt:
gpu_mem_1024=304
hdmi_mode=32
over_voltage=0
force_turbo=1
over_voltage_sdram=0
core_freq=450
hdmi_group=1
initial_turbo=0
start_x=1
sdtv_aspect=0
disable_overscan=1
hdmi_force_hotplug=1
arm_freq=900
sdram_freq=450

Add smsc95xx.turbo_mode=N to /boot/cmdline.txt and report back if things are better or worse.

I added in the same day I opened the issue.
I did some speed test with GitHub - sivel/speedtest-cli: Command line interface for testing internet bandwidth using speedtest.net , before and after adding it
Didn’t noticed speed decrease.

My internet is 50Mbit/s and I get
Testing download speed…
Download: 29.75 Mbit/s
Testing upload speed…
Upload: 14.27 Mbit/s

Will keep monitoring transmission speed. But It was always inconsistent - before and after adding that. Oscillate ±20%. hdd is ext4.

Also did this which removed an cache error in journalctl about cache.
echo ‘net.core.rmem_max = 16777216’ >> /etc/sysctl.conf
echo ‘net.core.wmem_max = 4194304’ >> /etc/sysctl.conf
sudo sysctl -p
