You have a different book to most then.
I've always understood 'b' to mean bits, and 'B' to mean bytes. While everyone on here will understand what you were trying to say in context, given purely that number, I would expect most people to interpret it as 90+Mb/s = ~11+MB/s. That is not what you meant, hence why Bruce said be careful with the units.

I just had a quick look in 'systat -vm' and it seems to use a capital B everywhere from what I can see.
