Lattner on Swift (2016): "...while it is true that modern GC's can provide high performance, they can only do that when they are granted much more memory than the process is actually using. Generally, unless you give the GC 3-4x more memory than is needed, you’ll get thrashing and incredibly poor performance..."

Agreed. I would say 2x the heap size is table-stakes for high-performance tracing GC, and the more you give it the better performance you can get.
