I'm wondering: Is it possible to take a whole-system trace as benchmark? E.g by replacing glibc malloc, booting the system from 0, then placing some interesting loads. For every malloc/free/realloc, write to some file the pid,tid,size, process private bytes. Performance will probably be horrible, of course. This being HN, i fully expect someone responding that was the state of the art in 1970 and here is a site containing every possible trace ;-)
