bytes per second calculation

[Eugene MacDougal]

I am running MailScanner 4.60.8 with Postfix 2.4.3 on Solaris 10 (x86).  It
seems that when large mails are scanned, the "bytes per second" caclulation
comes out to 0.  When I send a very small message (2k or so), the number
calculates just fine.  I started to look at the code, but perl is not really
my thing....Here is a sampling of my MS logs
