The results are nothing short of astonishing. In two weeks time the NetBSD team made dramatic improvements. socket: previously O(n), now O(1). bind: greatly improved, but still O(n). Much less steep, though. fork: a modest O(n) for dynamically linked programs, O(1) for statically linked. mmap: a bad O(n) before, now O(1) with a small O(n) shadow. touch after mmap: a bad strange graph in 1.6.1, a modest O(n) a week ago, now O(1). http request latency: previously O(n), now O(1). Congratulations, NetBSD! NetBSD now has better scalability than FreeBSD. " __________________________________ Do you Yahoo!? Protect your identity with Yahoo!
