"I experienced the same issue after Tahoe upgrade. May Mac was totally unusable it was so slow. I looked at Task manager and started to suspect that corespotlightd might be the root of all my troubles. I deleted all files under ~/Library/Metadata/CoreSpotlight/ and restarted my Mac. Result was night and day and it has been running smooth as silk for several days now."
I couldn't be more pleased. After removing those files and restarting my M1 Mac mini everything has been stable and running fantastic for the past 10 days.
I hope the engineers at Apple are monitoring this thread and push out an update that incorporates this because Tahoe is great once you get past the major inconvenience.
To be clear my Mac was running very sluggish after the update to Tahoe. Windows would take forever to open, fields wouldn't populate the text written until long after I stopped pressing any keys, Zoom calls, FaceTime calls and phone calls would abruptly end without cause, and even searches through google felt like the early days of the internet. Thank you @AppleUsedToBeMyFriend you saved my regression back to the previous version.
