Looks like Adam/Mo might be a victim of his own success:
"Most users ever online was 528, Today at 03:19 PM."
with about 469 users on presently.
Which might explain the minutes to execute an action presently such as a load of a thread, search or post. What's more notable is how more loading on the server causes a cascade of more concurrent users, as it takes longer for every action to complete, thus slowing down response all the more. Oh well. I guess more folks need to press the 'donate' link so increased capacity/time-slices isn't all coming out of Adam's pocket.
