Not always. Remember that TCP is a _byte-stream_ and that users of TCP
should (generally) have no interest in or knowledge of the segment size.
TCP will break "large" user sends into segments, and combine small sends
into full-sizes segments.
UDP will had whatever you give it to IP, which will then fragment it as
needed. If your send size in a UDP test is smaller than the MTU-8 that
will generally be the packet size.
If you enable TCP_NODELAY (generally not a good thing to do), and your
sends are less than the MSS, that will generally be the packet size.
If your sends are larger than the MSS or MTU, the packet sizes will
depend on how much larger the sends are relative to the MTU/MSS.

That is probably a function of the operating system. If it is running
Unix, getconf() may help.

Throughput = totalworkperformed/elapsed time
