batch processing tmes

[Dave Filchak]

OK .. I think I have my configuration straightened out and am not seeing 
errors in spamassassin -d --lint or sa-update -D. However, what I am 
seeing is batch processing times all over the map ... sometimes 1 - 3 
seconds and then often times up as high as 25 -30 seconds. Can anyone 
shed some light as to what might be causing these long processing times. 
These are happening with batches of only two or three messages.
