Reorder active pages to improve swap performance

A computing device comprising:

• a processor configured to execute a memory management subsystem;
• and
• a memory comprising volatile and non-volatile memory, the processor and memory being configured to:
• locate page table entries associated with a plurality of pages associated with a process in a first data structure in the volatile memory, the process having a low likelihood of execution in comparison to other processes,
• copy the plurality of pages to a second data structure in the volatile memory,
• copy the plurality of pages from the second data structure to a third data structure in the volatile memory at the same time, and
• write the plurality of pages from the third data structure to contiguous blocks of non-volatile memory based on the plurality of pages having been written to the third data structure at the same time.

A non-transitory, tangible computer readable storage medium, encoded with processor readable instructions to perform a method for using volatile and non-volatile computer memory, the method comprising:

• locating page table entries associated with a plurality of pages associated with a process in a first data structure in the volatile memory, the process having a low likelihood of execution in comparison to other processes,
• copying the plurality of pages to a second data structure in the volatile memory,
• copying the plurality of pages from the second data structure to a third data structure in the volatile memory at the same time, and
• writing the plurality of pages from the third data structure to contiguous blocks of non-volatile memory based on the plurality of pages having been written to the third data structure at the same time.
