Linux 7.0 Shows Off Nice Performance Gains For Databases In Small AMD EPYC Servers

Last week with my ongoing testing of the in-development Linux 7.0 kernel I found nice performance improvements for PostgreSQL and other workloads when testing on a 128-core AMD EPYC 9755 "Turin" server. Curious if those wins were due to optimizations focused on better scalability with today's "big" servers, I also ran some comparison Linux 7.0 benchmarks on the smaller AMD EPYC 4005 class servers too.
