I don't think it's possible right offhand to adjust that - it's a sendmail
function rather than a listserv function - normally the length forwarding
is invoked when there is a heavy load on the system - if the load is
light, it normally goes ahead and mails in the sequence received. It's
somewhat like batch operating systems principals. You wouldn't want
to hold up a 10 second job to run a 3 hour job in front of it (resulting
in a turnaround time of 3 hrs for the long job, and 3 hrs, 10 secs
for the short job). Since we only have a single fractional T1 line into
the internet backbone, when it saturates things back up a bit.

Right now for example (14:10 local) we have 229 messages in the queue
waiting to be delivered. At that load, probably things will go
out sequentially. But when we get to 500-600 messages built up, then
length forwarding goes into effect. The most likely time for that
to occur is when the digests are being mailed (since much of the 
1,000 member list is in digest mode). But since that is normally done
in the early morning hours (depening on how many digests are generated
in a day) we don't usually see a bunch of incoming posts at that point.
