Classification: CPC G | IPC G

Claim 5:
6. A system, comprising:
a first level memory device;
a second level memory device;
a virtual memory manager to perform:
generating, during system initialization, data structure information indicating that system data structures, generated during system initialization, are one of swappable data structures and non-swappable data structures based on estimated frequencies the system data structures will be accessed, wherein the non-swappable data structures are estimated to be more frequently accessed than the swappable data structures, wherein the non-swappable data structures are maintained in a first level memory device and not moved to a second level memory device, wherein the first level memory device has lower latency than the second level memory device, wherein the system data structures are identified as having a file name or object name and comprise configuration information for the system generated by an operating system;
maintaining access counts for the swappable data structures stored in the first level memory device;
selecting a swappable data structure in the first level memory device having lowest of the access counts of the swappable data structures in the first level memory device;
removing the selected swappable data structure from the first level memory device; and
retaining the selected swappable data structure in the second level memory device.
