SO far I have seen no real significant changes in throughput or latency, (judged by ministat). I, however, am only one person and I would love to see if anyone could confirm this. just compile two (otherwise) identical kernels, but one with options VIMAGE_GLOBALS. and perform teh same tests on each and put the results in ministat. any network test you can imagine is fine.. thanks Julian (off to DisneyLand for a few days with the kids).
