Hi, having a VM sitting (a) in loader prompt or (b) in ddb> makes the fans go loud on a test-laptop which makes one wonder if we can avoid that. Note -- I assume also on real HW though that's less likely observered here. For example I am sitting in a 4 vCPU bhyve current in ddb> and two threads are at 100% on the base system. Do we need to heat up the planet doing that or are there alternatives? I haven't looke dta the code in ages and I assume we need to poll in these situations on the console and for interactivity often enough? Can we "pause"? And why would two [v]CPUs be at 100% and not just one as I would expect all but one to be stopped? /bz -- Bjoern A. Zeeb r15:7
