This is correct, it's an Internet link with 100Mbps on one side and 3 bonded E1s on the other. We are using a commercial product (running on windows) now and it is able to sustain 5Mbit/s so I have to believe that FreeBSD could do the same. -Max -----Original Message----- From: Dave [Hawk-Systems] [mailto:dave@hawk-systems.com] Sent: Wednesday, July 09, 2003 10:45 AM To: Max Clark; Simon Cc: freebsd-isp@freebsd.org Subject: RE: How do I max a 6Mbps link >Let me give a little more detail.

My initial guess would be that you don't have a 6mbps dedicated pipe across the atlantic and that your packets are competing for bandwidth, thus the reduced actual throughput. If you put the boxes side by side, they could easily max a 6mbps link, as such the problem exists on the network (or the WAN link for that matter). Check to see if you have 6mbps dedicated, not only at both ends, but through all the hops in between. Dave
