I tried setting kern.sched.steal_thresh=3D0 as per crest@rlwinm.de direc= tions. There is no effect. 2. I tried the install of Release 12.4 instead and there is no more lag. However, I believe this bug affects both 13 and release 12. I will need to investigate this issue through other channels instead to avo= id hijacking the thread. --=20 You are receiving this mail because: You are the assignee for the bug.=
