Not "hundreds of megabytes on a single core", 5 GB per second on a single core on a i7-6700HQ. Use `openssl speed -evp aes-128-ctr`, look at right-most column of 16kb blocks (like TLS record layer).

Is the conclusion that redis doesn't handle caching items that reach 99MB size each? I guess I would cache them in blob storage, not in RAM. And make sure to zstd them.

No. If your projectile reaches altitude of target satellite with 0 velocity, hangs for a moment and starts to fall down, but then is impacted at relative velocity of kilometers per second by a satellite, your weapon (or Kessler syndrome tri

I think they mean something like SSE/AVX, but with something like ARM Scalable Vector Extension (code that works on registers with 128 to 2048 bit size, unknown at compile time).
