    Hi @ismcagdas, I have updated the nuget packge and then run the tool called jetbrains for profiler and refreshed the page and found only refreshing the page is tasking almost 575mb of memory and aslo if you can see the unmanaged memeory it also 264 mb

    and in second screen shot if you can see the unmanaged memory it showing 314mb at that time I am not using anything application is in ideal mode

    and aslo please let me know how the objects are getting disposed in your applicate becuase I did not find IDisposable interface anywhere

    Thanks

    Hi @shedspotter

    I have a few more questions.

    1. Do you use Redis in your app ?
    2. How many users are actively using the system.
    3. Do you have any "async void" methods ?

    Thanks,

    Hi @shedspotter

    It is really hard to reach to such a CPU usage with 15 users. Aare you able to reproduce this on your local environment ? If so, can we also test it with your solution and try to find the problem ?

    Thanks,
