Slow Application

Question

Slow Application

ANB 181

My project MVC has grown and now I see some slowness increasing.
What would be the best way to check the entire system (MVC, .NET, JAVASCRIPT calls) and figure out where the bottleneck or slowness is coming from ?
Setting something like StopWatch for each method ? or there is something better ?

Thanks

There is no magic to troubleshooting. The first step is reproducing the problem consistently and getting a baseline measure of "slowness".

Start with the browser's dev tools which can give you an idea of what process is taking a long time. Are there a lot of images and content that take a long time to download. Maybe the server side rendering is taking a long time. It could be the client side rendering depending on your application design or the libraries you are using. You could have poorly performing DB queries. Maybe database tweaks are needed.

There's a lot of things to look into and check. Just start troubleshooting and eliminate one thing at a time.

Hi @ANB ,
As far as I think,If your application is the first, slow is normal.You could check your performance:

You could add some debugging statements that spit out elapsed time in your Application_Start() method or any other applicable location to try to catch what's taking the longest.
You could create a completely clean demo project and deploy it. See if it suffers from the same problem. If it doesn't try introducing more and more of your real code until you detect a slowdown.
