WinSCP slow speed SCP/SFTP – How I fixed it
old servers I knew were capped at 10Mb/s, so when WinSCP reported 1MB/s I was actually happy with it, so I stopped paying attention to it.
Recently I noticed that even from 1Gb/s and 100Mb/s servers, WinSCP was still downloading at 1MB/s so I got curious and then little frustrated when I noticed culprits were always the same servers, while others ranged from +4.5MB/s.
I changed most relevant settings but the one that actually worked was to disable Connection -> Optimize connection buffer size.
Cheers
