Nope. FTP uses clean raw streams for binary transfers, no encoding at
all. ASCII mode transfer does CRLF conversion but noone should use ASCII
mode for benchmarking. Binary mode is OK.
I usually use a large file that consists of a large hole and then 1KB of
data for FTP benchmarking (and transfer it to /dev/null on the target
machine) to avoid disk bottleneck - when ttcp is not at hand.
