If you mean 600k bits per second, then you have a problem. If you mean 600k bytes per second then that may just be as good as it gets. 400k or so was the best I could get out of an NE2000 on a 486DX33 w/ 8MB thru two routers. Same path these days with faster CPU's yeilds 600k or a little better. SGI O2 to FreeBSD P-133 runs about 750k to 850k/sec thru an http://www.onsale.com $39.96 8 port 10baseT hub. As others have asked, "what are the conditions?" For starters: -) what CPU, speed, memory, and FreeBSD version on your server? -) what are you connecting with? What ethernet card does it use? -) how large is the benchmark file? -) network: a remote hub with wires in the walls? a direct conection to the client? a flea market $20 hub under the table? any routers?

This link could be running full duplex but I don't know how to tell the Mac how. :-) -- David Kelly N4HHE, dkelly@nospam.hiwaay.net ===================================================================== The human mind ordinarily operates at only ten percent of its capacity -- the rest is overhead for the operating system.
