I was able to upgrade my catalina 10.15.7 to big sur 11.0.1, the problem now is the machine becomes laggy and almost impossible to use sometime. for instance, when I play music on spotify, it produces strange noise sometimes indicating that it is freezing for a second at some point. Not sure how to troubleshoot this. Would accept any suggestions.

—Rebooting several times after an upgrade can sort anomalies.
—a SafeBoot https://support.apple.com/en-us/HT201262
Takes noticeable longer to get to the login screen, does a 5-15 minute disk repair before it fully boots up, and certain system caches get cleared and rebuilt, including dynamic loader cache, etc. Login and test. Reboot as normal and test as caches get rebuilt.
—Test issue in another user (or guest user) account https://support.apple.com/en-us/HT204443
if no resolve you can re-install the macOS on top of your existing macOS

Yes, it's weird that after the upgrade, the the upgrade button is still available, what I did was I "reupgraded" using that button, and removed all of my external I/O, it seems to be better now.
Slow and laggy after big sur upgrade
