I networked two computers (a Dual 500 G4 and a fairly new 1.25 GHz 15" PowerBook) with a FireWire cable, but the transfer speeds are quite lacking. Now, I've done this once before, and I remember the speeds being very fast, but I'm not sure what's changed since then. I have a 15 foot FireWire cable which I initially used, but then used my super super short Apple FireWire cable as well, and both showed the same speeds, so I'm led to believe it's not the cable.

I tested the speed in two ways. The first way was FTPing a single large (>1GB) file between machines, and I got about 11 MB/sec. Thinking the hard drives *might* be a bottleneck, I then used netcat between the two machines to generate as much (non-disk-dependent) UDP traffic as possible, and that maxed out at around 12 MB/sec.

Any ideas why it won't run any faster? It's FireWire..I should be seeing much faster, speeds than Ethernet, right? Am I just missing something stupid?

(I'm not the only one that this happened to. Another member of the forums here is having the same problem.)
