I'm not aware of something cross-platform that rakudo offers for memory use of a process, and getting the size of individual variables is an extremely hairy topic. You can use the --profile=heap target to get full snapshots of all objects in memory whenever GC kicks in, and go through it with the moar-heapanalyzer tool jnthn made. I had a pull-request open for an op i called "vmhealth" that would output a bunch of statistics including what the different allocators are doing, but progress halted when I didn't get input or came up with good ideas for what else to include. Here's the PR: https://github.com/MoarVM/MoarVM/pull/536 The reason why "memory in use" is difficult is because of many things not having a single owner. Imagine an array, where you could have bound the individual containers to any amount of lexical variables, for example. Also, if there's exactly one Rat in the whole program, do you count the presence of the class itself as being used by the variable that holds that Rat? hope that sheds some light - Timo
