I.e. is it more or less aggressive depending on what the OS tells it about available memory? Or does it do the same things regardless of the memory pressure. I’m asking because I’m not sure how to communicate that memory pressure in a containerized environment-- or if there is even a need to do so. …

It scales the GC rate with the available memory, yes. I think people who have studied memory allocators usually suggest a maximum ratio of about 1:5 for expected maximum memory to maximum physical memory. Beyond that, it starts to taking exponentially longer to allocate and free memory. There is an…

To add a few details to my question: (cross-posted from #helpdesk on Slack): in this case I can just bump the memory limit on my kuberbetes pod, but my question is more about the semantics of how Julia’s GC works with regards to memory pressure. E.g. if I set a memory limit of 16 Gb in kubernetes, …

Does the GC respond based on memory pressure?
