Linux Fake NUMA
The machine that
https://friendica.eskimo.com runs on is an i9-10980xe, this is an 18 core, 36 thread processor, all cores overclocked at 4.5Ghz with 256G of RAM.Typically the CPU is about 10% occupied and 90% idle, but still sometimes processes are slow or stall. Disk I/O likewise is not saturated, and out of 256G of RAM typically about half is in play and half is available.
So I am doing an experiment in a bit in which I am using NUMA emulation to divide the memory up into four fake NUMA nodes and treating the memory as if a NUMA machine even though it isn't. The idea is that by having four parallel memory controllers instead of one, memory allocation lock contention will be greatly reduced, and since there is no cross-node penalty I hope this won't be expensive and will pay off in better performance.
We will find out in about an hour.

The Scale of God
Take a moment on a dark clear night to go out and look at the sky, if the sky is clear you might be able to see two or three thousand stars in sky, You can see the zodiacal lights. If you really pay attention you can see a smudge here and there, the most prominent of which is the Andromeda galaxy. Realize now that the universe contains around 2 Trillion of these within our visual horizon and even more beyond that, perhaps an infinity.
Each of those two trillion galaxies contains on average about 200 billion stars. That's around 4 x 10^22 stars, about 1-in-8 of those will have a planet in the Goldilocks zone, the habitable zone where liquid water can exist. Of these only a portion will be stable enough, have the right chemistry, not be tidally locked, be around a star that isn't so angry that it strips the atmosphere, to develop complex life, maybe 1-in-1000, but even if 1-in-a-million that is still 4x10^16 planets hosting complex life, and a non-trivial percentage of those will develop intelligence because the survival value of intelligence incentivizes it's development in evolutionary terms.
So our God likely presides over somewhere around 10^22 intelligent species in the portion of the universe we can see and likely much more beyond that, perhaps even an infinity.
Do you really think such a God could be owned by one tribe on one planet? Do you think such a God would encourage one tribe of his creations to slaughter another? I don't.
