ABSTRACT:
A method may involve assigning each of a plurality of freelists and a plurality of hashlists used to implement a cache to one of a plurality of lock groups and acquiring one of a plurality of locks. Objects on each freelist and hashlist that are assigned to the same lock group are allocated from the same one of a plurality of memory allocation pools. Each lock group is associated with a respective one of the plurality of locks. Acquiring the lock locks a freelist and several hashlists included in an associated lock group of the plurality of lock groups.
