A Look At Linux Application Scaling Up To 128 Threads: Arriving last week in our Linux benchmarking lab was a dual EPYC server -- this Dell PowerEdge R7425 is a beast of a system with two AMD EPYC 7601 processors yielding a combined 64 cores / 128 threads, 512GB of RAM (16 x 32GB DDR4), and 20 x 500GB Samsung 860 EVO SSDs. There will be many interesting benchmarks from this server in the days and weeks ahead. For some initial measurements during the first few days of stress testing this 2U rack server, here is a look at how well various benchmarks/applications are scaling from two to 128 threads.
