How does this compare to a normal, non-VERPed delivery for this list?

grep -E "1..... recips" logs/smtp

 May 27 16:43:46 2004 (440) <[EMAIL PROTECTED]> smtp
         for 151942 recips, completed in 1231.438 seconds

1231.438/151942 = 0.0081046 seconds per recipient (average)

 Jun 30 15:39:26 2004 (435) <[EMAIL PROTECTED]> smtp
         for 152717 recips, completed in 428.891 seconds

428.891/152717 = 0.0028084 seconds per recipient (average)

         for 152991 recips, completed in 31782.241 seconds

31782.241/152991 = 0.2077392 seconds per recipient (average)


So, on average, you're taking somewhere close to 25-75 times as long, if you enable VERP for the entire list. Ouch!


        I ask because Chuq Von Rospach has done some calculations on what
 should theoretically happen to your performance if you enable VERP,
 but I don't know of anyone who has actually timed the performance
 difference on large lists.

Usually the sending (mailman to postfix to 90% of users) takes a bit more than two hours ; yesterday it took about 6 hours. But more importantly, the Mailman -> postfix thing took 5 hours instead of ~ 15 minutes.

I will definitely update the VERP performance entry in the FAQ to reference your experience.
