...this comes at the cost of not being able to mmap the bytecode, though. In other words, we save 10MB of disk space, but cause each invocation of Rakudo to eat up 11MB of data memory instead of being able to (potentially) mmap a shared copy. > In the long run it might also be possible to come up with a more compact > PBC format, but I guess that's much more work than compressing and > decompressing. Perhaps Lorito will be able to help here. But ultimately the real savings (both memory and startup time) will come when we can truly serialize Rakudo's subroutines and constant data structures. Pm
