Hi, current 64bit support uses compressed reference pointer by default, i.e., a 64bit reference is stored as a 32bit value plus a (global) base address. This can reduce the footprint of working set and at the same time improve cache locality. But this has max heap size limitation.
I wonder why not use non-compressed pointer as by default, and the compressed pointer is only an optimization that can be applied when desirable. Comments? Thanks, xiaofeng
