Click Advanced button on Login dialog, while setting up a new site or editing an existing site.

As documented here:

How do I get to the advanced site settings to optimise the connection buffer size?
Not obvious to me :?

Thanks

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

Though, in C#, you should use .NET assembly:

Can we do it through C# coding as well.The Host is not communicating for more than 15 seconds.

winscp.StandardInput.WriteLine(sftpUsername);
winscp.StandardInput.WriteLine(sftppassword);
winscp.StandardInput.WriteLine("dir");
winscp.StandardInput.WriteLine("ls");
winscp.StandardInput.WriteLine("mkdir " + path); // path is the folder structure that needs to be created
winscp.StandardInput.WriteLine("cd " + path); // path travesered.
winscp.StandardInput.WriteLine("put " + zippath); // file needs to be put from my system
winscp.StandardInput.Close();
string output = winscp.StandardOutput.ReadToEnd();
LogMessageToFile(output);

Is there a better approach

Dear team,

I am not able to connect a system and got message that Host is not communicating for more than 15 seconds...if problem reoccurs try turning off optimize connection buffer size . But I am using winscp5.7.7 and dont find this option. Could you please guide me where exactly this option is or how to resolve this issue.

Regards,
