Benefits of Disable Debug Mode in ASP.NET
What activity happens on the server when we leave debug mode is true? #1. It disables page timeouts #2. It disables compiler optimizations to make symbols close to the actual source code statement #3. To improve compilation time, it disables some of batch optimization #4. Increase memory footprint of the application #5. Disables caching of WebResources.axd (browser will download the associated script files again for every page), #6. Disables compression of WebResources.axd resources #7. Disables both page and JIT compiler optimizations To enable or disable debugging, update the debug value in Web.Config accordingly compilation debug="true/false" But, if you want to enforce all site(same server) owner then make the below update in Machine. Config #1. This will enforce the 'debug' flag to false in every web.config on the machine. #2. It will disable page output tracing and custom error pages to be shown to remote users instead of the real error
