Question Browser respone time - serioulsy affected

[sargan]

W10 ver 21H1

Starting today my Browser (Chrome) is taking ages to respond on sites ....
For example, I go to tlc-direct.co.uk do a search ... and it is minutes before I get any response.
Same if I try with FireFox

Side by side if I do a search on my phone (Firefox) response is less than 2 sec, against 2 min or more on PC

Task Manager does not show any processes hugging processing, but it does show Ethernet running high - 100kb and almost flat lines when I try a search.

No issues on this site for example - so assume it's something to do with searches.

I have reset Chrome, reset Router, rebooted PC ...... still very very slow

Rest of PC uses seems fine ... video, FB, email etc.

If you're on 21H1 for Windows 10, you have an update pending. See if that helps. I'd also make sure that your motherboard/platform BIOS is up to date as well.

I downloaded and applied that .. and it seems to have fixed it, wonder why it suddenly started misbehaving
