WebThe rpmalloc benchmark is not included in the artifact, so we adapted it to output similar results. These benchmarks were conducted on a 16-core 32-thread workstation with 2 Xeon E5-2620v4 CPUs on the WSL. We benchmark these workloads at 1, 2, 4, 8, 16, 24, and 32 threads. For the (1-8) thread configurations, all use physical cores.
