I got those types of numbers (~40 secs) when I was using the broken patch. Without any patches at all, my adjustments were -100 seconds, not +40. There probably should be at least some difference between unpatched and patched. For the sake of my sanity, can you please build a GENERIC kernel from scratch without any patches and capture the above output and then apply http://www.FreeBSD.org/~jhb/patches/i8254_lapic.patch and rebuild and capture the same output again? -- John Baldwin <jhb_at_FreeBSD.org> <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve" = http://www.FreeBSD.orgReceived on Wed Jun 29 2005 - 16:30:46 UTC
