Are the rubies built with, or allow using, jemalloc? #610

Closed hms closed 3 months ago

First, thank you for this wonderful time saver!

Are the current builds using jemalloc? Or if not, is there a way to optional args my way into jemalloc?

I'm struggling with OOM issues with a very action build and test config and noticed that my local environment that is built with jemallc use ½ to ⅓ the memory during testing and was hoping there was an easy way to explore if that might solve the problems (at least for now).

Thanks in advance.

That's not available and it would be too much work to add and double the number of builds. The alternative to have only jemalloc builds is also problematic because it's a non-default and probably less stable config.

Maybe https://bugs.ruby-lang.org/issues/15667 can help (e.g. using 3.3 or setting MALLOC_ARENA_MAX).
