Yes, although IMO, that statistic is largely useless if SA is involved.

SA's scan time is much more a function of message count than of message
size, particularly if DNSBLs are enabled. Although it's actual timing is
really quite widely scattered it's certainly more correlated to the number
of messages in a batch than the size of the batch. Large body sizes increase
SA's scan time a bit, but that's usualy drown out by the time it takes to do
DNSBLs.

Also, bear in mind that the timing is done in whole-second increments and
the rounding makes for some hefty errors. (ie: if a batch is 5k in size,
even if it takes .1ms to scan it, it will be reported as 1 second and
5k/sec.)
