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 h= ave attributed various slowness in bhyve guests to the use of spinlocks when ma= ny 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. --=20 You are receiving this mail because: You are the assignee for the bug.=
