Cruisin' On Kernel 6.16

I configured, built, and installed kernel 6.16 today (10 minutes
total time, including Nvidia modules).
I configured the X86_NATIVE_CPU option, of course.
Do I notice a speedup?
Fuck no! I am a human being. I interact with the computer
though a GUI, and all GUIs are necessarily very slow.
To actually measure a performance increase I would have to compare
virtual memory allocation, context switching, I/O throughput, and
many of the other functions that the kernel performs and which
are beyond the reach of human perception.
But, whether I can sense it or not, it is there.
Most importantly check this:

Holy holies! I am vulnerable everywhere!
The bogey men are ready to pounce. The gremlins are poised to strike.
I am doomed to die a horrible death.
Ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha!
The security toadies cause more damage to my digital sensibilities
than any "vulnerabilty" ever will.
