https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=278535 John F. Carr <jfc@mit.edu> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jfc@mit.edu --- Comment #1 from John F. Carr <jfc@mit.edu> --- I notice delays of several seconds around the "launching APs" message. I have attributed various slowness in bhyve guests to the use of spinlocks when many CPUs are contending for the lock. If not all of the virtual CPUs can be scheduled simultaneously then each will use its full time slice spinning waiting for a suspended virtual CPU to finally run and release the lock. -- You are receiving this mail because: You are the assignee for the bug.
