Interesting to note it was one 32 byte function in those registers netting a 10% speed increase. Reminds me of demo scene tricks. That function was for sure hand written assembly/machine code. It is something of a lost (and not needed by most people) art these days.

I feel like the nineties demoscene equivalent is taking over the machine (x86) and putting some code and important variables into cache lines that never get evicted and all of your data runs through the other cache lines by mapping of that data sparsely in memory.
