that's very interesting with some blunt ending
But if the objects being scanned are already located on the same page, aren’t we just wasting time managing the page and tracking the objects within it?

Tangential but this makes me think of a video about C# GC, and the developer switching to Swift to avoid it, in which the dev says they estimate the development of a pause-less GC to be 5B$ R&D away, does that ring the bell to anyone?
Excellent optimization technique: manually copying objects to a new slice so they don't prevent the GC from releasing memory by sitting right in the middle of a page it intends to free.

This was very interesting, but the ending was a bit abrupt. I was under the impression that there was something more that I was missing under the subscribe banner.
But to the point of the article - are there cases in which manually moving objects around to compact them in a specific area is done with golang? I don't use golang that much, and I'm sure that there are very strong arguments for not compacting the heap post-GC, but I've always wondered how it avoids crashing in the 0.0001% of cases in which heap is defragmented in such a way that there's no way to allocate a new large object
