Safari extremely slow after upgrade to Tahoe 26.2

I'm using a MacBook Pro M2 and upgraded to Tahoe 26.2 on 8 January. As of this morning, Safari is so slow as to be practically unusable. I cleared the cache and history, set Spotlight to NOT show related content or help Apple improve search, saw that nothing was taking too much CPU percentage, closed everything, restarted the machine. Even after this, websites are extremely slow to load, and sometimes load first with corrupted visibility, i.e. text appearing over other text, and buttons not reacting. It has taken me over 30 minutes to log into my Apple Community account and search the boards before being able to ask this question. Is anyone else having this particular problem? Is there anything else I can do to avoid it?

MacBook Pro 13″, macOS 26.2

Not here with 3 different M-Class computers each with Tahoe 26.2

Restart the computer in Safe Mode

Do the issues persist ?

Sometimes a Safe Boot followed by a Normal Boot will just put things right.

If not - there could be something in the main User Account playing up. To further isolate this - Set up users, guests, and groups on Mac. Then log out of the Main User account and log into the dummy account and test again if the issue persists.

If the issue is present in the dummy account - then, this appears to be a System Wide issue on the computer.
