Linux Benchmarks

I created two computers with identical hardware, and run the benchmark programs in both starting at the same exact time.

What makes no sense is that the computer that has the lower average index (121) finished the race a good 30 minutes ahead of the computer wich showed the higher avg index (167). The only difference here were the operating systems, which I am not naming yet because it may have commercial implications, and frankly I need to understand the results before jumping to conclusions. Maybe lower index means better system? That would be absurd.

Anybody has any idea about what is happenning?
