One embodiment of the present invention facilitates skewing a bi-directional object layout to provide good cache behavior. During operation, the system receives a request to access an object. This request includes an object identifier and an object offset that specifies the offset of a target field within the object, wherein the object has a bi-directional layout that locates scalar fields at positive offsets and reference fields at negative offsets, so that a reference field can be immediately identified from its object offset. Next, the system determines a skew value for a cache line containing the object, wherein data within the cache line is shifted based upon the skew value, so that reference fields with small negative offsets are likely to be located in the same cache line as scalar fields with small positive offsets. Next, the system uses the skew value in accessing the object.
