Hmm. To verify, I just ran it on a PPro 150, 2.2-STABLE circa Oct 1st: fcntl: 13.9273 secs ipc: 11.8795 secs On a PPro 200, 2.2.5-STABLE from today: fcntl: 10.9368 secs ipc: 9.40272 secs Now for the interesting part, a Pentium 166MMX: fcntl: 9.64589 ipc: 7.66043 Could it be a weird PPro thing? The only other difference in the 166 kernel is that the FASTER_5X86_FPU (something like that) is turned on. Oh yeah, the kernel is 2.2.5-STABLE from today as well. I'll see if I have an older machine/kernel around and try out some more tests.. -Mark > > > > > > John > > -- ------------------------------------------------------------------------ Mark Mayo mark@vmunix.com RingZero Comp. http://www.vmunix.com/mark finger mark@vmunix.com for my PGP key and GCS code ------------------------------------------------------------------------ Win95/NT - 32 bit extensions and a graphical shell for a 16 bit patch to an an 8 bit operating system originally coded for a 4 bit microprocessor, written by a 2 bit company that can't stand 1 bit of competition. -UGU
