ok, but even then the benchmarking results would most likely be a bit different, since modern CPU's tend to have quite different cache sizes and I/O respectively memory bandwidth. > I implemented this a while ago and then accidentally lost the sourcetree > but I did do some profiling which I can't find now :( no problem.
