Can Docker-OSX save a running state on disk ?

Seems that Docker-OSX has permance issue : Startup is slow ,it takes 5 mins+ to complete the system startup to see the whole desktop. But after the completed startup everything becomes more smooth.

The CPU usage of host system is low ,the CPU useage of qemu process is often blow 100%(8core CPU,800%) .Memory is not be fully used in guest system(memory used in 1.8G,cache in file 3.8G,swap??But host system has 16G mem ,12G mem in qemu process ). Disk IO is showed low in iotop on host system.

Docker-OSX is based on qemu ,I know qemu can save guest system running status. Could Docker-OSX add this feature ? And disable swap in OSX ？ I can not bear this slow startup speed and lag UI control in OSX big-sur . Thanks
