Huw Thank you, that ruins that theory! I don't see any error messages. I have recorded the send times for one of our forums, it takes around 5-6 seconds to send each subscriber an email (a very constant figure for each subscriber), which fits in with the total time to complete a topic with 11 subscribers of almost a minute before control is returned to the poster. With subscriptions turned off it only takes about 2 seconds. Is there anything I can do to track down why it takes so long? Sending an email to myself from within the forum software completes within a second or two so why should emails generated from inc_subscription.asp takes so much longer? Nick
that is a bit strange, I would expect them to have similar send times. I'll fire up a VM and do some testing using cdo to see if I can determine a reason for the difference.
Huw, any progress? I am going to try AspEmail if I can arrange for the necessary files to be loaded on to the server. Do you have any experience of that service? Nick
