[CLOSED] Performance issue on ASP.NET MVC application using ext.net
Hi,
We are facing some performance issues in our MVC application developed using ext.net 1.7. The components are rendered programmatically.
We tried to time our server side processing to see if the issue is caused by our code using the Stopwatch
class provided by .NET. The results were very conclusive and we were able to eliminate a performance issue within our code.
Performance tests are done on one single local dev environment.
Here one of our views within the solution
Add to that, we are facing a render lagging (empty panel) that takes at least 6 seconds in which no ajax request is executed as logged within firebug (or may be the ajax request is blocked). This lag is really problematic for the end user experience!
Then the screen is rendered and combo's store are loaded using HttProxy, but here too the Ajax request is taking too much time than expected. The server side treatment is about (2ms per combo box on average) while the request ajax execution time can take 3 seconds per combo which is too long as shown below.
We thought that the problem came from the max http request property within the browser but changing the value from 6 to 100 within firefox didn't resolve the problem.
So, to recap we would try to find a solution for the lag. We would like also to know why the ajax requests are taking more than the expected execution time.
Your help is really appreciated as this is becoming an urgent (showstopper) performance issue in our production environment.
Thank you in advance,
