i'm not sure what "good performance" means. is there enough functionality in current µkernels to even benchmark real work against plan 9? the original problem posed was the "scalability of linux development". how does l4 help with linux' development problems? i tend to think the problem is in goals and mgmt. as a case in point, > And instead of revising the design, I think we're going to see them go > for the 2-percent speedups here and there. from what i've seen, there's a funny math to linux optimizations. a number of 2% µoptimizations lead to global 12% pessimization. - erik
