64-bit vs 32-bit

As 64-bit machines become more common, the problems we need to solve also evolve. In this post I’d like to talk about what it means for the GC and the applications’ memory usage when we move from 32-bit to 64-bit.   One big limitation of 32-bit is the virtual memory address space - as a user mode process you get 2GB, and if you use ...
