What are the typical data rates for small and for large messages?
You get this from the postfix logfile records.
postfix/smtpd client=x.x.x.x gives the approximate start of transmission.
qmgr size=xxx gives the message size and approximate end of transmission.
Combining these gives you the data rates.
