The strange thing is that using FileZila/WinSCP on any server limits the transfer speed / file to 1.5MB/s The ping between PC and the server which has the big files: 42-43ms It may be the IPS but not sure, I think it has something to do with some config which got overwritten and that limits the speed and I don't know which and where would that be. The same netcat and pv between the server which had the big files and my PC using Ubuntu from witin Windows got me 111MiB/sĪll transfers are now slow at 1.5MB/s even between the servers and that's pretty annoying, because I can transfer 10 different files and they would all transfer at 1.5MB/s, but if it is only one file, the speed wouldn't increase.Īlso disabled firewall for every machine and still same issue.

On source server: pv On destination server: nc -ulp 5000 > /dev/null.Using netcat and pv between the servers showed up to 113MiB/s using this method: I tried using rsync and tar cf - * | pv | netcat ip 7000 I have also other servers with same OS but different kernels, but the problem is the same there, transfering files are limited to 1.5MB/s (and haven't been before - when I installed them and transferred what I needed on them). I've tried to make the file available to transfer via http, but the same 1.5MB/s speed. I once had a 30GB file to transfer, and had to wait for around 6 hours. Haven't done anything on server to the configs, just regular apt-get update & apt-get upgrade I usually download with my PC from Steam with 70-80MB/s, so bandwidth issues wouldn't be a problem. Now in the last 2 months the file transfer speed dropped to ~1.5MB/s (stays between 1.4 - 1.6 MB/s). I usually download the backups from the server once a week or so, which are 3-5 GB tar files.įor the first 4 months I had the file transfer from the server to my PC around 20-25 MB/s.

The problem I encounter is that for a few months the transfer speed over single files have slowed down. I have a server from where I download big files with the following specs:

Filezilla install ubuntu 20.04
