Description:

Did you ever want to know how fast your tar is or how much data it has
transferred already. How about using socket or nc to copy files either
with or without compression over a fast network connection, which one
is faster?

If you want to know the answer, use cpipe as a totally unscientific
approach to measure throughput. Cpipe copies its standard input to its
standard output while measuring the time it takes to read an input
buffer and write an output buffer. Statistics of average throughput
and the total amount of bytes copied are printed to the standard error
output.
