Earlier this month in our initial benchmarking of DragonFlyBSD 6.0 we found DragonFlyBSD 6.0 performing much better than DragonFlyBSD 5.8, but how does that put its performance up against FreeBSD 13.0 and Ubuntu Linux for reference? Here are such benchmarks in our latest benchmarking of DragonFlyBSD 6.0, FreeBSD 13.0 (with both GCC and Clang), and Ubuntu Linux.

Plus there are new features with the latest generation of Intel graphics such as the Protected Xe Path (PXP) for hardware-protected sessions for multi-user / multi-process scenarios. The Intel PXP code for their Linux driver has been in the works since last year and the latest revision now submitted...

As usual when getting my hands on a new processor family, I was curious about the performance difference if booting the Xeon Platinum 8380 "Ice Lake" processors with the Spectre security mitigations disabled at run-time. Ultimately there was very little difference when using the standard "mitigations=off" option for these new Intel server processors...

Earlier this week when posting Ubuntu 20.04 LTS / 20.10 / 21.04 benchmarks on the new Intel Xeon Platinum 8380 "Ice Lake" server processors, one of the first questions that came up was about how well these new 10nm server CPUs perform with Intel's own Clear Linux distribution. While Clear Linux releases have become much less frequent and far less to communicate these days on new improvements/optimizations among other ongoing shifts with that Intel open-source project, it is still performing very strongly with 3rd Gen Xeon Scalable hardware. CentOS in these tests also had a strong showing with the increasing performance focus on that front.
