Speed Up WinSCP downloads for SFTP and SCP connections
On your login screen, select your SFTP or SCP connection then click 'Edit', then click 'Advanced...':
![select edit, advanced on your SFTP or SCP connection](/_next/image?url=%2F_next%2Fstatic%2Fmedia%2Fwinscp-login-edit-advanced.1c4564fe.png&w=1920&q=75)
Select 'Connection' in the list and try disabling 'Optimize connection buffer size':
![Select connection, then disable optimize connection buffer size](/_next/image?url=%2F_next%2Fstatic%2Fmedia%2Fwinscp-optimize-connection-buffer-size.38a55785.png&w=1920&q=75)
In my case this increase speeds from ~10kbs up to ~2.5 mbps.
Hope this helps,
Duane
