Hello I try to investigate performance issue about calling api from web ui

Our Architect is

IIS Web -> HAProxy -> K8sIngress -> API

Then i use dynatrace to check where it slow.

I Found That it Spend a lot of in WebUI Not API Side so i check further.

See That Session is consume a lot of time.

How can i find what the root cause for this? Or I need to Contact Microsoft?

IIS version 10.0.14393.0

You should go to host => edit and there you can enable early adopter feature about IIS Modules tracking:

after this you will see which module is rootcause. You have to restart iis after this change.

I look Further and See the Session Module is the problem.

But What i can do next to improve performance.

Dynatrace will not help you more here. Problems with session module may have various of reason on IIS

You should check IIS forums that are corresponding to this topic.
