Firewall - enabled, DOS protection - disabled.
Once again I want to remind you that there is no problem in version 380.65_04, and in other versions there is a problem.
The settings are the same everywhere.
With firmware 380.65_4, the download speed is approximately 9 Mb/s - the processor load is approximately 85%
With firmware 380.67, the download speed is less than 4 Mb/s - the processor load is approximately 97%
At the moment when the problem exists, I use only torrents.
I do not write about the built in router torrent client, but about the usual qBittorent.
I am connected to the provider via VPN.
I do not use other VPN services.
100 Mbit
Yes, I am sure.
Now I installed 380.65 again - there are no problems.
I think the problem is connected to the VPN protocol - L2TP
Yes, it's enable.
I can attach a couple of screenshots for comparison:
