👁 Algebraic Multi-Grid Benchmark benchmark with settings of . Linux 6.11 Git 64K PS was the fastest.
It's typically with the heavier HPC-type workloads that benefit the most from going with a 64K page size on AArch64, but the performance impact can vary.
For those running AArch64 servers/workstations with demanding software, it's certainly worthwhile evaluating a 64K page size kernel to see if the performance benefits are worth it as they can be very lucrative for many applications.
As mentioned earlier, the prior AmpereOne benchmark/review articles were already using a 64K page size kernel for reference so these gains aren't "new" per se but just illustrating the benefits clearly in this article to the larger page size.
