Subject: [ruby-core:28746] [Feature #1047](Feedback) request: getters, setters for the GC

Issue #1047 has been updated by Yusuke Endoh.

Status changed from Open to Feedback
Target version set to 1.9.x

Hi,

> I've attached a patch adding getters and setters for HEAP_MIN_SLOTS and GC_MALLOC_LIMIT.


My personal opinions:

- Though I think a few rough "modes" is acceptable (e.g., -server and
  -clients of Java), such a specific parameter tuning is not Ruby way.

- The name `malloc_limit' is very arguable because it is too specific
  to implementation-detail of MRI.

- HEAP_MIN_SLOTS is just referred when the interpreter is initialized.
  So I guess dynamic change of HEAP_MIN_SLOTS makes no sense.

- I cannot reproduce performance improvement as shown by Roger. Could
  you show me a self-contained code to run benchmark?

Thanks,
