Only insofar as spam tends to be small (spammers go for quantity, not
quality ;). Scanning large messages takes lots of time and resources
(CPU/RAM).
So as you increase the size limit of the messages that you scan
you quickly get to the point of diminishing returns (IE catching
few addtional spam but taking more time/CPU/RAM on your server).
On a busy or limited server you could cut that down (say 100K) with
little loss of filtering hits. Checking a random sample of 1000 spam
in my spam-trap folder, 80% was under 25K almost all the rest
was under 100K.
