This would be an alternative way of doing the same..
Code:
awk '/Speed/{print int($2)}' xx

if it's not 1000Mb/s, it's Mb/s1000,this method will be useless?

Code:
awk '/Speed/ && match($0,/[[:digit:]]+/){print substr($0,RSTART,RLENGTH)}' inputfile

I can't think of any that are as simple. IMO, you would need to use (g)sub functions or FS or the split() function.
