We deployed our web app on azure and found that the app is performing poorly. So we ran the diagnostic test on azure, results of which is posted below.

The diagnostic report also says that >90.91% of failures came from '/signalr/reconnect' path.
Is this something to do with Abp Notification System? If so, how can I disable the notification system?

@sparkyjr as you said, it seems like a signalR problem. Does SignalR connects when you open the website ? You can open your browser javascript console and check if there are logs like "Signalr is connected".

Hi,
All seems normal. SignalR tries to reconnect automatically when the connection state is disconnected. But I'm not sure if it can cause a high cpu usage or not.
Which version of ABP do you use in your project ? There was a memory leak problem and fixed in this issue <a class="postlink" href="https://github.com/aspnetboilerplate/aspnetboilerplate/issues/2629">https://github.com/aspnetboilerplate/as ... ssues/2629</a>.

Hi,
You can see the integration steps of SignalR here <a class="postlink" href="https://aspnetboilerplate.com/Pages/Documents/SignalR-Integration">https://aspnetboilerplate.com/Pages/Doc ... ntegration</a>. So, basically, you need to remove those parts from your project.
After all, I suggest you to search for SignalR in *.js and *.cs files. There might be some parts which are not metioned in the documentation.

To disable SignalR without removing it, just remove the FEATURE_SIGNALR constant from all .csproj files, e.g. Web.Mvc.csproj
