No, there really isn't.
> 2.58s is the slowest run of the fastest pidigits on the node page, but one of its runs took 1.04 seconds.
Notice column N — 2,000 6,000 10,000.
That's a command line argument passed to each program, controlling how many digits of pi are generated — the workload.
So, 2.58s for 10,000 digits and 1.04s for 6,000.
(And as it says, there can be a cold caches effect on the first measurements.)
