What about #ASYNC hangs?

Those are even more gnarly to debug ...

Here is our new guide on fixing async await hangs in aspnet core, mvc and webapi apps! https://t.co/gUqhNWqHzg

You are probably WAY overpaying for your cloud CPUs.

See why, and fix it.

Hangs are the most common performance issue for IIS and ASPNET sites.

Fix these with our new guide! https://t.co/H0Wjdljvye

(We've just added some big improvements too, more details shortly)

Step 2: HEAL your website by fixing top errors, and slow requests!

Literally watch your quality of service go up.

https://t.co/4oAHhiedUE

[LeanSentry @LeanSentry]

What if you could stuff ALL the info on errors and code causing slow requests right into your IIS logs?

It's a crazy idea, but also the best idea ever.

Do it with the latest ApplicationMonitoring.dll, see how at https://t.co/CB7JrSllxK

Many .NET web apps we see are "inelastic": they choke under pressure instead of stretching to the load.

(Result: poor performance at peak load, more servers, more cloud $$$)

Here is why and how to fix: https://t.co/v1fb2iFPoU

[LeanSentry @LeanSentry]

Tune w3wp.exe CPU usage AT THE RIGHT TIME, and you can ... fix 503 queue full incidents, prevent high CPU hangs, and cut hosting costs.

[LeanSentry @LeanSentry]

We do a lot of cloud cost reductions by tuning w3wp memory usage.

@aspnet @inetsrv @csbowles Thanks! Happy to hear, we do what we can :)

[LeanSentry @LeanSentry]

Back with more IIS performance guides after a short break. Next up, the IIS thread pool.

(Nothing to do with hangs, but a lot with 503 Queue Full, and CPU overloads).
