I did and saw pid 17 [zfskern{txg_thread_enter}] using lots of CPU but no disk activity happening. Do you see similar?
I will try and report back.
Can you try https://reviews.freebsd.org/D7538 and report?
The patch tells it is against -STABLE, we're talking -current here.It has been a while since I tried Karl's patch the last time, and I stopped because it didn't apply to -current anymore at some point.
Will what is provided right now in the patch work on -current?As a data point, the system I talk about in the start of the thread has 64 GB RAM and the ARC is not limited via sysctl.
