AMD 4th Gen EPYC "Genoa" To Enjoy Slightly Better Performance With Linux 6.3
For workloads with high kernel interactions like carrying out lots of I/O is one of the areas where Automatic IBRS provides a nice, measurable uplift compared to the current Linux kernel running with Retpolines on AMD EPYC 9004 series processors currently.
Networking workloads on AMD EPYC 4th Gen should also find slightly better performance too when moving to a Linux kernel that enables Automatic IBRS usage in place of Retpolines.
Some OpenJDK Java workloads may also enjoy some slight performance improvements when switching over to Automatic IBRS.
