Re: [Gems-users] instruction count

[Dan Gibson <degibson@xxxxxxxx>]

The number of instructions reported by ruby is a delta between the 
initial instruction count and the final instruction count. The number of 
instructions reported by pstats is a total instruction count, staring at 
boot-time if I am not mistaken. Hence the discrepancy.
