can real time in benchmark.rb be less than the other other ones?

Question

This is my benchmark.rb output. Is it not weird that real time is less than ther system and total time? or is it okay to have it? I am new to ruby, please forgive me if I sound stupid. Thanks!

user     system      total     real
1.050000   0.000000   1.050000 (0.503462)
1.533333   0.016667   1.550000 (0.735473)
1.500000   0.016667   1.516667 (0.711239)

My guess is that you ran this on a dual core machine, or at least a multiple core, and it ran two threads.
