ubuntu server 12.04 кто то режет скорость
Собственно проблема такая: server 12.04 , стоит lamp, ssh, proftpd.
Кто то режет скорость сам так и не нашёл, в каком плане режет : хоть по ssh закачка/скачка файлов в том числе wget хоть по ftp , хоть через веб интерфейс ограничена 2 мб/с. С начало грешит на конфиг proftpd отключил шейпер и тд не помогло.
А потом оказывается все системы режется. Подул на tc но там в нём не разобрался. Собственно вопрос может кто знает в чём причина неизвестного шейпера.

Ubuntu 20.04 Network Performance Extremely Slow
I just upgraded from Ubuntu 18.04 to 20.04 on one of the Dell XPS 13 machines, and the network performance is abhorrent. Internet speed is very fast from a google speed test (>300Mb/s for both upload and download). However, whenever I try to browse a website or even run sudo apt update the connection will often time out. My internet is very fast on all other devices and I really don’t know how to debug this problem.

It seems like this is a pretty common problem, and one without a definitive cause. For me, it was because Ubuntu resets the TLP configuration, and the power management went back to «on». I disabled Wi-Fi power management directly by editing:
sudo nano /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf Then changed the value from 3 to 2, saved changes and rebooted. I actually got this solution from Reddit and this worked for my case specifically but it seems like it could be caused by a bunch of other things. Read all the proposed solutions below!
