IIS7 - only serves up one page at a time. It's a making me crAzY!

Question

Situation: Classic ASP application, using a custom Application Pool. Default settings.

On some IIS7 machines, IIS decides to serve only one page at a time.

Answer 1

In IIS manager click on the application in the tree.

Double click ASP under the IIS section.

Expand "Debugging Properties"

Ensure both "Enable Client-side Debugging" and "Enable Server-side debugging" are set to false.

When debugging is enabled ASP is limited to processing one request at a time in a single threaded manner.
