can you help explain the question about the RAM used by snap

[wangzhenkeep]

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%
