not intending to pour gas on the flames, but there have been a number of
ukernels since that are a fraction of the size of p9 (and less functional,
by design). Some with very good performance.
i'm not sure what "good performance" means. is there enough
functionality in current µkernels to even benchmark real work
against plan 9?
you can microbenchmark the ukernel itself and run macrobenchmarks
on operating systems sitting atop the ukernel.
btw, there's even been one ukernel recently that has a formal
proof of correctness (against its specification and some containment
properties). Roughly a 10 man-year effort for about 7.5kloc.
Not something you'd likely be able to do yet against something linux-
sized.
the original problem posed was the "scalability of linux development".
how does l4 help with linux' development problems?
no idea.
