AmpereOne Performance On Linux 6.11 Kernel, 4K vs. 64K Page Size Comparison
When it came to the performance benefits of upgrading to the Linux 6.11 kernel from Linux 6.8 (with the default 4K page size), the LULESH HPC benchmark enjoyed a nice 6% boost from the new kernel.
The Linux kernel build time also was reduced by just over 5% when the AmpereOne Supermicro server was running on this very fresh kernel that incorporates all of the upstream kernel innovations over the v6.8 kernel from early in 2024.
Consistently across all of the GraphicsMagick OpenMP-threaded imaging application operations, the Linux 6.11 kernel was showing off some rather nice improvements compared to the Linux 6.8 kernel as shipped by Ubuntu 24.04 LTS.
In a variety of other benchmarks carried out, Linux 6.11 delivered similar or slightly better performance... Some small gains here and there, not too bad for just being the course of a few months worth of upstream Linux kernel enhancements. The upstream Linux kernel continues moving in the right direction for AArch64 just as I frequently showcase with x86_64 on Intel and AMD platforms with my frequent kernel performance benchmarking. Though with only having my hands on this AmpereOne server for a few weeks, this will be a one-off kernel comparison.
Let's move on though to the three-way with the Linux 6.11 64K page size kernel for more interesting data.
