Hi Mathias,
I m using MC 9 final on Win10 Pro x64.
With me, MC is fast but when I do connect to FTP then it take long time to scan folder and sometime it error as below.
With WinSCP and "FTP in totalcmd", they load structure folder is faster MC.
I don't like compare with others FTP but I only mention these FTP client here so that you can improve performance of loading structure folder in FTP when you have free time.
