This is not what I'm mostly concerned about. The patches create a bottleneck since _all_ processes use the same resource. Plus, this code has to be run on a machine with multiple processors to get RFOs into play. So, please do this: on an SMP (4p or more) machine, rig the test so that it runs quite a while. Then, in a script, start the program a bunch of times, all in parallel. Have the script wait until all program runs are done and time the time until the last program finishes. -- ➧ Ulrich Drepper ➧ Red Hat, Inc. ➧ 444 Castro St ➧ Mountain View, CA ❖
