The progress bar with the speed indicator tells me of about 95,000 kbytes/s; ETA within a few minutes.
Reality looks a bit different. Turn minutes approximately into hours, divide speed by something like 60 to 100 and you've got a more down-to-earth picture.
Havn't tested with (built-in) FTP so far, so I don't know whether it's the WebDAV plug or TC.
