Phoronix: DragonFlyBSD Gets Performance Tuning For Threadripper 2990WX Topology, Scheduler Tuning

While it was just days ago that DragonFlyBSD lead developer Matthew Dillon got his hands on a Threadripper 2990WX 32-core / 64-thread "beast", got it working under this long ago forked operating system from FreeBSD, and proceeded to exclaim with joy how powerful this system is, he's now made it even better. Dillon has landed some additional kernel work to benefit the AMD Ryzen Threadripper 2990WX...

DragonFly is the only OS that is built from the ground up with a very deep consideration for scalability of thread/core/socket and asymmetric NUMA. Matthew Dillon had a clear vision, and we can see the results now.

Remember also when looking at the benchmarks, that DragonFly is using the HAMMER2 filesystem, which is a high-availability COW (on steroids) filesystem, while the linux benches use ext4 and xfs. This is not a criticism on the benches, but an observation. I believe the benches use the recommended FS from the distro, which is good methodology. But HAMMER2
