I don't think it's in maintperl yet, and I haven't seen a bleadperl snapshot in a long time. I'll try to set you up with something off-list. > I could give it a try on an SMP machine. > Is there any ad hoc testing to try? There would be value in simply running the standard test suite with the above configuration, but offhand I don't see anything in it that would really stress readdir_r. To do that you'd need to write something that does an opendir, then starts multiple threads, each of which does readdir on the same directory stream. Doing this on a fast mirrored disk or RAM disk would help factor out I/O completion as a serializing influence.Thread Previous
