I have, for specific problem applications. While I can neither provide specifics on performance differences (most of the performance tuning engagements I've performed have been under blanket NDAs) nor proof that the specific applications are representative of CF apps in general, my conclusion was that this option significantly impeded performance under load (50+ concurrent users). I'm not sure why, exactly, this causes a problem; my guess is that there's only one request queue, and if two requests from the same session are next to each other in the queue, subsequent requests won't process until the first request is complete, even if there are available worker threads. This is, of course, pure speculation. You might ask someone on the CF Server development team for more detail about how this option works.
