Note that support for large files (> 2GB) in the current Kermit
releases is limited to pure 64-bit platforms like Tru64 Unix.
Preview versions of the next C-Kermit release are available here:
http://www.columbia.edu/kermit/ckdaily.html
This version supports transfer of large files, both with Kermit
protocol and FTP, on many platforms, listed here:

As to speed, you can measure it yourself but modern Kermit is
a lot faster than many people imagine. It has been adapted to
today's relatively transparent and error-free transports (TCP/IP,
error-correcting modems, big buffers, etc) to go at speeds close
to the connection speed itself; sometimes a bit faster due to
a simple built-in compression method.
