How does this compare to a normal, non-VERPed delivery for this list?
grep -E "1..... recips" logs/smtp

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.
