So I don't know what the units are, or even if "in" means "in" to my client or "in" to the grid!!!
Anyone got a clue?
Update:
Having dug though the source code it looks like it's in bps and that "inbw" is the speed in to the client which I kind of guessed, but it's nice to know!!!
And no doubt you'll be bemused to know that it doesn't make that much different in world

I think structures seem to load faster after a tp, but textures seem to take about the same time. Probably the bandwidth throttling kicking in and taking me back to where I was before I fiddled
Ah well!
