This is a 6Mbps internet link that traverses the atlantic and 25 router hops. "out of the box" I can only sustain 170KBps. We are currently evaluating a REALLY expensive commercial solution, but I would rather know I was going to be paid than spend $50K per link. What can I do to help freebsd saturate this link?

FreeBSD out of the box on low-end Intel hardware can easily sustain 6mbps link, which is roughly 3megs/sec. Make sure your harddrive on receiving end can write at least this fast and your network is capable of such transfers. Sometimes faulty switches/cable wires can cause packet loss/delays, causing a bottleneck. It could be a number of things, but I would start with testing your network. -Simon On Wed, 9 Jul 2003 10:12:03 -0700, Max Clark wrote: >Hi all, > >What configuration changes do I need to make to two freebsd-stable boxes to >fully max out a 6Mbps/220ms network link?
