Config is a CF/iMS machine relaying through an outbound gateway, a 1 GHz 
FreeBSD box.  The "connection time" is the average session time seen by 
SMTPD process on the gateway from the time CFX-ims connects to the ip of 
gateway, sends one msg, and disconnects. (ie, delivery to internet is not 
included, this is across a LAN)

The 200 msg test was a hard-coded loop with an empty msg, avg connect time 
was 4 secs per msg.

Using the real list server app with a 21 kbyte msg, delay is 45 to 60 secs.

Here�s the report section:

Per-Hour SMTPD Connection Summary
     hour        connections    time conn.    avg./conn.   max. time
     --------------------------------------------------------------------
     1400-1500        327         0:31:10           6s          34s
     1500-1600       1460        24:17:17          60s         255s

Just before 15:00, the 200 msgs were sent plus 127 "application" msgs.

Since 15:00, only the applications msgs have been sent.  Removing the 127 
app msgs with 60 sec delay, from the 327, we think the 200 test msgs 
averaged about 4 secs.

The question is why are the app msgs taking 10 to 15 times longer?

The LAN is 100 megabits, so we are sure the physical transit time of 21 
kbytes of app msg is not a factor vs the empty test msgs.

The gateway also delivers several 1000 msgs at just 2 secs/msg to a 2nd 
"garbage collection" relay that has all the deferred msgs dumped on it.

The gateway has 40 to 70 SMTPD dynamic processes running accepting msgs 
from iMS box.  It�s these SMTPD processes that are connected 45 to 60 secs 
each to receive one msg.
