I upgraded my MacBook Pro M3 Nov 2023 to Tahoe 26.1. Safari seems to take a bit (1/2 second maybe) longer to load/return results, this is a "feeling" no evidence. I have checked my network connection and it is within download/upload speeds prior to upgrade. I am curious if others have experienced this or just my imagination. Please comment if you are aware of similar experiences by users.
MacBook Pro 14″, macOS 26.1
For a while after any system upgrade, your Mac will be busy in the background, when awake but not too busy. It re-building the spotlight index.
In Tahoe and later, it is also re-analyzing your photos, recognizing key features to be able to manipulate your pictures more easily, using recognized objects and faces rather than a mash or pixels.
The 'company line' that goes with this analysis is that it is taking place, privately, on YOUR system, to avoid even copying your PRIVATE data onto any Internet Server for analysis.
By far the easiest way to cause poor performance, instability, overheating and crashing is to install ANY third-party speeder-uppers, Cleaners, Optimizers, Virus scanners, Bit Torrent, or a VPN that you installed yourself.
¿Are you running anything like that?
VPN:
A virtual private network, or VPN, is a private connection over the Internet from a device to a specific network. VPN technology is widely used in corporate environments. If you need to be "present" on an institutional network, a VPN is a great tool for accomplishing this. It is generally issued and controlled by the institution.
Almost all other uses are a SCAM. There is generally no need for you to have a private (and almost always MUCH slower) connection to a VPN vendor's Network, except to make it easier for them to harvest your data to sell. If you are behind a Router you control or Trust, there is NO security advantage whatsoever in using a VPN. Your connections are already encrypted in most cases.
If VPN vendors just stopped there, it would be bad. But many of these packages also insist on scanning all your files, non-stop, -- nominally looking for viruses, but who knows for sure what data they are harvesting. Their non-stop file reading punishes your computer's performance in the process.
Some also break into your other secure connections so they can be FIRST to examine your data, often leaving your Mac MORE vulnerable to attack.
What VPN service to use? DON'T use VPN services

Well, what do you know, I think you solved it. I do have a VPN running, forgot about it. Installed it day before Tahoe 26.1 upgrade. Thank you.
Is Safari slower on MacBook after Tahoe 26.1 upgrade?
