Since test4 came out I ran a bunch of tests
again to gauge performance. As you'll see test4
is a little slower in some cases as compared to test3 ... I also had some compile problems with test4 in networking (pcnet32), but others have compiled without problems. All the foll. tests were on EXT2, on a 2 CPU X86 box with 64MB memory. Test3 numbers were the best I've seen in a variety of kernels including 2.3.42, 2.3.99pre2 and several intermediate "pre" versions.
