Fast initialization of complex in-memory data structures

A computer program product comprising one or more computer-readable storage media having thereon computer-executable instructions that are structured such that, when executed by one or more processors of a computing system, cause the computing system to perform a method for restoring a state of stored configuration data of an application component that is be executed on the computing system, the method comprising:

• requesting mapping of a least a portion of a backing page file to a second portion of address space, the backing page file being stored in a persistent storage, the backing page file comprising discrete units of configuration data that are stored in a specific relationship to each other as defined by one or more offset values, wherein a first base address for at least one of the discrete units of configuration data defines a first portion of address space having a first preferred address space address for the at least one of the discrete units of configuration data;
• and
• restoring the at least one of the discrete units of configuration data stored in the backing page file to the second portion of address space, comprising aligning a pointer based on a relationship between a second base address of the second portion of address space and the one or more offset values to thereby restore a state of the at least one of the discrete units of configuration data, the first base address being different from the second base address.
