Linux benchmark is slightly slower than the FreeBSD one. The Go version is also a bit older. I tried the same with the up-to-date version of Go (1.24.x) with similar results. There could be a slight Bhyve overhead, or FreeBSD is just slightly more efficient in this benchmark. Overall, this shows that Bhyve performs excellently.</span><br /> @@ -480,15 +475,15 @@ http://www.gnu.org/software/src-highlite --> by Lorenzo Bettini http://www.lorenzobettini.it http://www.gnu.org/software/src-highlite --> -<pre><font color="#ff0000">root@freebsd</font><font color="#F3E651">:~</font><font color="#ff0000">/git/sillybench </font><i><font color="#ababab"># go test -bench=.</font></i> -<font color="#ff0000">goos</font><font color="#F3E651">:</font><font color="#ff0000"> freebsd</font> -<font color="#ff0000">goarch</font><font color="#F3E651">:</font><font color="#ff0000"> amd64</font> -<font color="#ff0000">pkg</font><font color="#F3E651">:</font><font color="#ff0000"> codeberg</font><font color="#F3E651">.</font><font color="#ff0000">org/snonux/sillybench</font> -<font color="#ff0000">cpu</font><font color="#F3E651">:</font><font color="#ff0000"> Intel</font><font color="#F3E651">(</font><font color="#ff0000">R</font><font color="#F3E651">)</font><font color="#ff0000"> N100</font> -<font color="#ff0000">BenchmarkCPUSilly1 </font><font color="#bb00ff">1000000000</font><font color="#ff0000"> </font><font color="#bb00ff">0.4273</font><font color="#ff0000"> ns/op</font> -<font color="#ff0000">BenchmarkCPUSilly2 </font><font color="#bb00ff">1000000000</font><font color="#ff0000"> </font><font color="#bb00ff">0.4286</font><font color="#ff0000"> ns/op</font> -<font color="#ff0000">PASS</font> -<font color="#ff0000">ok codeberg</font><font color="#F3E651">.</font><font color="#ff0000">org/snonux/sillybench </font><font color="#bb00ff">0</font><font color="#F3E651">.</font><font color="#ff0000">949s</font> +<pre>root@freebsd:~/git/sillybench <i><font color="silver"># go test -bench=.</font></i> +goos: freebsd +goarch: amd64 +pkg: codeberg.org/snonux/sillybench +cpu: Intel(R) N100 +BenchmarkCPUSilly1 <font color="#000000">1000000000</font> <font color="#000000">0.4273</font> ns/op +BenchmarkCPUSilly2 <font color="#000000">1000000000</font> <font color="#000000">0.4286</font> ns/op +PASS +ok codeberg.org/snonux/sillybench <font color="#000000">0</font>.949s </pre> <br /> <span>It's a bit better than Linux!
