sorry,My English is very poor. I found a strange phenomenon about RAM .when I use command "-t 1",the proportion of RAM is from 0.6% to 24%.But when i use command "-t 2" or "-t 4",the proportion of RAM changes between 0.7%,4.6%,1.0%,5%.I provide a form.

-t cpu / RAM time1 time2 time3 time4 time5
1 CPU(percent) 100% 0% 100% 0% …
1 RAM(percent) 0.60% 24%
2 CPU(percent) 200% 200% 0% … 200%
2 RAM(percent) 0.70% 4.60% 0.70% … 4.60%
4 CPU(percent) 400% 400% 0% … 400%
4 RAM(percent) 1% 5.50% 1% … 5.50%
