Abstract: The embodiments described herein include methods and systems for improving the performance of application virtual machines by extending an object store corresponding to the application virtual machine. The method includes identifying a subset of migratable objects from a plurality of objects associated with the application virtual machine, where the subset of migratable objects includes one or more objects and the plurality of objects are stored in the object store comprising a portion of the memory allocated for the application virtual machine. The method also includes selecting a respective object from the subset of migratable objects to be migrated from the object store to a persistent datastore, where the persistent datastore is distinct from the object store. The method further includes causing the respective object to be migrated from the object store to the persistent datastore.
