There’s more benchmarks for DragonFly vs. other systems on Phoronix. It has the same problem as previous benchmarks; some of the benchmarks may have no connection to reality (what does the “Himeno Poisson Pressure Solver” actually test?), and almost every system has a different version of the gcc compiler. So it’s meaningless in terms of comparative or absolute performance. On the other hand, DragonFly doesn’t do badly.
You can also look at the comments to see someone absolutely freak out over the very existence of things that aren’t Linux. I’m not sure if it’s actually trolling, since the comments are so exactly wrong.
