How does a buildworld -j (> 1) go ? All the way to the end :-) Seriously: I haven't done any timings yet. I'm mostly just upping the load to see how stable it is. A -j4 completes and a -j8 is in progress. If that completes I'll be doing UP vs. SMP comparisons. There's a visible speedup, so things look good. I hope to have hard data next week or so. Random notes: o It should be safe to enable interrupt delivery to all CPUs and play around with programming the TPR of the CPUs. o SMP works with 4BSD only, but raj@ just told me he has ULE support for SMP. o We should take advantage of the OpenPIC timers to driver hardclock, etc. o Cache prefetching hasn't been enabled on the AP yet. -- Marcel Moolenaar xcllnt@mac.com
