Interesting. I always wondered why attachments increased in
size the way that they did. You've in fact brought up another variable
that I was not even considering which makes a direct comparison based
on time and the raw speed of transfer using TB! vs. an FTP client to
transfer the same file difficult to objectively compare. Another
variable is that connection speeds to my mail server vary between
sessions and within sessions and this is the same with ftp. Using a
stopwatch and concluding from the findings that TB! transfers faster
to the server byte for byte (irrespective of what the bytes are made
of) than transfer via ftp seems undoable in the circumstances. :-/
Of course you're very valid variable that 7bit encoding
increases the transfer size significantly makes these other points
moot. :)
