SShSimple documentation vs Forum comments are different

https://winscp.net/eng/docs/rawsettings

The documentation states "The SshSimple may need to be set to 1 to disable some of the optimizations, that unchecking the GUI option disables. "

However, on a lot of the forums, it states that sshsimple should be set to zero.

Example:
https://winscp.net/forum/viewtopic.php?t=15777

I am getting the optimize buffer errors. I think it might be that our FTP server is slow, but there is not much I can do about the FTP server.

Thanks in advance, Margaret

P.S. I love WinSCP and think it's a great tool

The documentation is (of course) correct.

Btw, I assume you are connecting to SFTP, not FTP server.
