Well I wasn't going to run it at full speed (whatever that might mean), but limit it to a relatively low speed, to get the jitter measurements for UDP in the hope they'd be a decent indication for how a voip call might fare on the same connection. If you have ideas for a better tool, I'm all ears. :) The other tests are done with netperf and good old ping. =2DToke =2D-=20 Toke H=C3=B8iland-J=C3=B8rgensen toke@toke.dk --=-=-= Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.19 (GNU/Linux) iQEcBAEBCAAGBQJQtAI6AAoJEENeEGz1+utPGrcH/iD/Yj1V+oCf2a47xKhxUKX8 tFvsGoB++wrLPJVGMmC96x/y6AlfcyfoPZASRbfgZIuv3MqTByfTmO69eXdLzhpE Y8KFqcLPFL62lCM2B65NTAoveRRgch7hoax6TspMIEztHvIM47ZDvW7JagS6IhNs lkarbihbsV+srW3eMNgX8dKtVCr1fkvkjVOLRAjb2eRXTtt0xZRmFZLoqRay70/l 0QzeTamwIhDIRASnx0m4/8ZOQbGv6crHtkFRl23AXAZ0vQXjDchDKuJHrMuX6p7o piz4dQPEAIdsIUIIeGs+LbbnK7A7qYOPcm/DrFd/kG1Mvnv8YxZ4z7sMFQadjz8= =DRzD -----END PGP SIGNATURE----- --=-=-=--
