Linux 6.15 Delivering Some Performance Gains On AMD EPYC For AI, HPC & Databases
Database workloads at large seemed to all enjoy small but consistent performance improvements running on the Linux 6.15 kernel compared to Linux 6.14.
While Linux 6.15 started out bumpy with the performance regressions spotted at Phoronix, in the end the new stable kernel is running well on the servers tested so far... Predominantly AMD EPYC with my Intel Xeon Granite Rapids reference server still being in a faulty state.
Slightly better context switching performance was observed with Linux 6.15.
Potentially explaining some of the Linux 6.15 performance improvements in the heavy AI/HPC benchmarks and database server workloads was observing some better scheduler performance on Linux 6.15 with the Schbench application.
Overall Linux 6.15 is running well on the hardware tested thus far from AMD Strix Halo to high core count servers. With the AMD EPYC 9005 series it was in AI/HPC and database workloads in particular that benefited from the newly-released Linux kernel plus some other workloads like some video encoding scenarios. In addition to some performance improvements are also new hardware support and other exciting kernel features with Linux 6.15. More tests are ongoing before turning our attention to the Linux 6.16 kernel now past its merge window.
