--Apple-Mail=_91438CEC-F202-4A0E-A7C5-0A96963EAB9F Content-Transfer-Encoding: quoted-printable Content-Type: text/plain; charset=us-ascii Hi, I have netmap working with the T6 cards now. However, performance is very poor. It seems to take several milliseconds = after a NIOCTXSYNC ioctl before the tail is updated? In case it matters, here is what is in loader.conf: hw.cxgbe.num_vis=3D2 hw.cxgbe.fl_pktshift=3D0 hw.cxgbe.ntxq=3D1 hw.cxgbe.nrxq=3D1 hw.cxgbe.qsize_txq=3D512 hw.cxgbe.qsize_rxq=3D512 hw.cxgbe.cong_drop=3D1 hw.cxgbe.pause_settings=3D1 hw.cxgbe.autoneg=3D0 hw.cxgbe.nm_rx_nframes=3D1 hw.cxgbe.nm_rx_ndesc=3D1 Lars --Apple-Mail=_91438CEC-F202-4A0E-A7C5-0A96963EAB9F Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename="signature.asc" Content-Type: application/pgp-signature; name=signature.asc Content-Description: Message signed with OpenPGP -----BEGIN PGP SIGNATURE----- iQIzBAEBCgAdFiEEmpq0ZpSoejRmyhheVLXDCb9wwVcFAltGGw8ACgkQVLXDCb9w wVfO4w/9GtwBdc3B45ShRyecErfzWyYsMc+Y6ESsSMAN5PRVaPzW1nKru8CFkDIx z1uxBTbQoktxkoMSBpqKLCZu2Pdz7D80qPg3WLl9F1q1mFKOUS6JdaeTirGdOfKG 5tP2/rMfb+ac9McbK8qmXM7xgG2pH4hoiEpRldaronz8XZH3FirNKtL1ayxtlga4 67WS7BQ8o2PglcN8QMVziG7k0hlcFXFxMrsVEDhkV/tu9SUR60el0zNc2vlH6MwI UvOtDnJywMDfyKX4+ejz05JHnpbAX9Wrw0iDDd/aiMSDnMFVtkdSP4FzTy5K4aW6 Mqj4WA35+HM4b2wZyz08mThFlzM7kvnj42EPhra2SCEl7a/SO0O45Nsj9VJQtTpL dPxXHMjZAeHAz2vBbuR6kHrpplpQKvgWc4lPqGL7+/Dv/8wYi8XSvkvsVv8qWfPN J/2iC3qZwRyrgcj46qsnnqALRs/bR7HTqaPvVzLo8KoN+t2g9mAk8ngSfOKA8Lvi sXT06OQj98yErWo5uRMevcX9ZJHnob4iVoTiBUvIRVUXTwNYBKgWGnzYhpTSFaUt EmSW1MIeVG+yCe8N8hc+z1kx5UWuFzx97Q4HqDvHb9n1IYGDkI70Jb7VKqvnR7xn d20EO8LKS9A1f43DOzC/V9mAiVEQ7A2y+qdpgZUBOlsUAYLt9fQ= =rwOB -----END PGP SIGNATURE----- --Apple-Mail=_91438CEC-F202-4A0E-A7C5-0A96963EAB9F--
