First of all - the explanation:
I have a web app I have developed that "functions" properly, just not optimally. Whenever I activate a control that causes a postback, the CPU on the server spikes to about 30% (w3wp.exe) and retreats to nothing within a few seconds. This causes considerable performance issues in both the front-end and the server. Whether it's a drop-down box that causes a SQL query through it's "SelectedIndexChanged" event, or just postback that massages data already on the form without a SQL call.
In an attempt to provide useful information, here is what I have tried and the results so far:
-- Looked at this, but I can already see what is causing my spike

-- Tried this URL, but I couldn't find anything out of the norm ...
