When I upload a file via SSH to my VPS server with Beeline mobile internet connection, the speed is about 300KB/sec – 800KB/sec:
But when I upload a file to the same server in the same way with Rostelecom internet provider, the speed is about 50 KB/sec:
and the upload periodically interrupts. The same result with uploading via HTTPS (Nginx + PHP).
Also when I connect to the server with a command line SSH client, it lags when I type a text in the command line.
While the download speed is probably acceptable:
Specially for smart guys from Rostelecom support: do not tell me that the upload speed depends on the severs where I upload the files to and do not tell me that I do not understand that the speed is really high and the files upload really fast and all the information I provided is wrong.
Experimentation with the modem
They replaced my old Tomson modem with Arris and now I have 1300KB/sec (about 1Mbit/sec) upload speed.
