If I increase GCSWEEPCOST and set the "setpause" value to a smal value(60),
the total time of sweep state becomes long(about 7 minutes  VS 30 seconds of the default GCSWEEPCOST),‍
during the 7 minutes, the average CPU's usage is  lower than ‍the usage on default GCSWEEPCOST setting,
but not smooth, the CPU's usage sometimes increases to a high value,  and decrease after a few seconds,

Oppositely, the total time of propagate state becomes short(about 1 minutes), 
the CPU's usage is smooth during the whole propagate state.
