We can use resume function to recover the system states base on the data in hibernation file in next time we reboot. Solid-State Drives is a new kind of storage device that have good performance in random access.Expecially random aceess speed is almost same as sequence access. So many embedded system use Solid-State Drives been the storage device. When operation system is working,almost 50%~60% date is come from storage device. These date is readed from storage device and copy into main memory. When hibernation cellect information to produce hibernation, so much read only data is cellected into hibernation file. The situation will make the size of hibernation to big.So we try to eliminate the size of hibernation file by swapping as much as possible memory page before hibernation start.
