I'm uploading a file through rsync and I found my upload speed is 10 times slower than what my ISP allows:
rsync -a --info=progress2 --human-readable --rsh="sshpass -p pass ssh -l me8" folder username@host:~/public_html/
I tried adding the -c arcfour option to decrease the level of encryption, with no luck:
rsync -a --info=progress2 --human-readable --rsh="sshpass -p pass ssh -c arcfour -l me8" folder username@host:~/public_html/
I also tried using ncftp as I don't really need the encryption, but I'm still getting the same limit:
ncftpput -u username -p pass -R host /public_html/ ./folder/
Now if I upload files through my browser, or if I test my connection on a "speed test" website, I get the full upload speed my ISP allows.
Note that I'm running Ubuntu 16.04 on a virtual machine, with the host machine being a Windows machine, and that I've found the same problem on this Windows machine: upload speed is limited in Filezilla but not in the browser.
I don't know what to check at the moment, any idea?
