https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D212681 --- Comment #22 from Roger Pau Monn=C3=83=C2=A9 <royger@freebsd.org> --- Hello, I don't have much time to look into this right now, could you try to create= a flamegraph [0] of this workload, this way we might be able to identify the bottleneck(s). If possible you should create the flamegraph with pmcstat instead of dtrace, the result is going to be much more accurate (specially = when running inside of a VM).
