Hi all, this is a small table I compiled to compare the performance development of the Linux kernel over the 1.3 series. Especially the xbench tests have a few gaps, but I think the general trend towards an improved performance is quite obvious. My comments are mostly guesses to explain the changes in the numbers. If somebody has better explanations, feel free to correct me.
