Classic ASP very slow when Windows Defender is turned on
And here we are again... 2023 and Microsoft is still neglecting to fix this issue.

Hi everyone.
I've noticed that when Windows Defender is turned on my Classic ASP applications get very very very slow. Something like 80% slower.
We can find some information about it on the internet, about people complaining about the same thing.
The issue occurs on Windows 10 1809 / 1903 and also on Windows Server 2019 1809.
This problem does not occur on Windows Server 2016 1607.
Some say that the problem is with vbscript.dll, but even if I add this on the exclusion list the problem still occurs.
The only way to make my applications running fast again is to disable the Real Time Protection, which is obviously not what I wanted to do.
I really need Microsoft to explain what has changed and what is the best way to address this issue and solve the problem definitely.
Thanks in advance.
After more than one year wainting for a reply on a reported and confirmed issue, Microsoft answered this in the Feedback Hub:

Well, it happens that the issue is still happening. I've added a comment on this issue inside the Feedback Hub, but no one answered me.
So the question is: Will you fix this for once and for all?
A lot of people are waiting to turn back on their Windows Virus Protection inside their servers when they have Classic ASP pages running.
Now, this ain't possible, because you didn't fix the freaking issue.
So please, fix this ASAP guys.
Thanks
