It doesn't run over the network.
The reports are requested from a website , and a record is inserted into the
And then the reports are run local on the Production machine and then
emailed to the recipient.

At this time only 2 people order reports.

Have you checked for network problems?  You might try FTPing a file to and
from the production server, or something similar, just to rule this out.

I've had slowness problems with various apps that were driving me *nuts*
until I found a network issue causing them.  In a few cases I had a duplex
mismatch -- an ethernet card set to full duplex connected to a half-duplex
hub/switch, or vice versa.  This results in a connection that appears fine
when you ping and works great under light traffic, but bogs down with
massive numbers of collisions as soon as you do anything that involves
moving lots of data.  The collisions may not show up in the statistics since
the end that's set to full duplex won't notice them.  Letting the card
auto-detect the duplex setting does *not* always work right...

This is a subtle, easy trap to fall into.  Easy enough that I've done it
multiple times. ;)
