Generally I don't get out of bed for less than a factor of 2. I'd probably 
make an exception for a library routine which will be used intensively by 
a large number of other people. Unless the optimisation was ugly, I might 
go as low as 5-10%.

Is the improvement consistent across a range of different compilers?
