"Resolving Host" is making the new Microsoft Edge unusable.

Yes that looks to be the location of the cache files / history.    Thank you.   Unfortunately it's not helping me understand why Edge goes so slowly after a while.   Had it have been writing these files to somewhere really strange and slow, I could perhaps understand it, but this is to s SSD drive that's pretty responsive.     The only other thing that might make a difference is the 64bit version versus 32 bit.   The problematic one is the 64bit version.

The files could be in 

*\Users\user_name\AppData\Local\Microsoft\Edge\User Data\Default\Cache*

I used Procmon to catch the Edge process reading and writing to files, this one stuck out as a good candidate for the cache files (if that is what you meant by temp files)

So just some further updates, but little progress at the moment.   I have three PC's all connected to the same router/hub and two of them work fine with Edge but have little usage.   The one I use all the time seems to suffer slowdown badly after 24 hours.   This caused me to question where the temporary internet files are held.   Everything I read says they are at 

*\Users\user_name\AppData\Local\Packages\Microsoft.MicrosoftEdge_xxxx\AC#!001\MicrosoftEdge\Cache*

HOWEVER through the many iterations of trying to fix this problem I deleted the Microsoft.MicrosoftEdge directory and forgot to reinstall it, BUT, I'm still using Edge and it does it's normal work for 24 hours and then slow down, but that directory still does not exist.... so where is it writing temporary files to?  Because it's clearly not here.

Second, as mentioned above, I have three PC's all running Edge, two fine (but with limited daily usage) and the main one is just problematic.   The problematic and one of the other two non-problematic PC's run Malwarebytes.   So if it is Malwarebytes causing the issue, why does it only impact one, unless again, it's usage related.

I've tried about everything with this and it's beyond frustrating right now.   I wish Microsoft would chime in on this and try to get to the bottom of the problem.   

PS - If anyone else knows where temporary files would be being stored if not above, would love to know.

Thank you for the tip on how to resolve the "Resolving Host" problem with Microsoft Edge by making a change in Malwarebytes settings. It worked....for now. Not sure why Microsoft doesn't answer with either fixing the bug or giving us these answers. Why do browser users have to find the answer????

Brian, I did the same just now and it works. We'll see for how long because someone last week gave me directions and it worked but 2-3 days later it didn't.

So thank you very much for this recommendation!!!

Does anyone get to talk to a real person at Msoft to determine what the hell they are doing about this issue? Not much from what I can tell as I just cannot believe they haven't communicated with us users about this issue.
