I got a Dell powerconnect 2724 gig switch, and have been testing it, but have not gotten the results I had hoped for.

Have been trying a number of things, and only about to get speeds similar to using a 100M switch??

When transfering with 1 sender and 1 receiver I can get speeds of between 300M and 400M with no retransmits. Set max bitrate to 400M to avoid timeout messages. Have done that with two different clients with same results.

When sending to the same two clients at the same time (or sending to 19 clients in another test) I only can get a speed of about 70M to 78M at best. With no options, it drops to 1M to 2M.

Setting the max bitrate seems to reduce the rexmits, but the setting of 80M. I've tried it with --fec 8x8/128 and without, and doesn't seem to make much difference.

It might be the something in the switch, but I have gone in, and disable the storm protection settings that I had though might be an issue early in the process?

The switch does have some limitations. Had to use an old 98 machine with old firefox to access its web interface, since it doesn't seem to work with newer browsers. Might just be this switch doesn't do well with multi-cast.
