`Collection.Hash` vs `Collection.Map` #460

Closed ghost closed 7 months ago

ghost commented 7 months ago

I'm totally ignorant about the algorithms underlying them and the use cases for each of them.

But this is what I observed.

I'm unable to have a Collection.Map with 1000000 elements. It always crashed with:

>>> call std::stack bounds have been exceeded! <<<

Increasing the value of --GC_THRESHOLD doesn't help.

But I'm able to have a Collection.Hash with 1000000 elements.

I have no idea why.

The call stack size is set to 32, rather small. I will create an enhancement to make the call stack and operation stack sizes configurable.

Tweaked the VM parameters yesterday to improve performance. The bottleneck was memory for both the Map and Hash classes when inserting 1 million elements.
