Great.

This is interesting. It seems a consequence on loading TCPHPTS, not actually using it.
I have CCed Drew and Randall, who know much more about HPTS and might have follow up questions. I'll bring the issue up in the FreeBSD transport call next Thursday. What hardware are you using? Best regards Michael > - Approx. results as test [2] > > > > > Nuno Teixeira > FreeBSD Committer (ports)
