Fragmentation rarely wastes more than 20% memory and 50% is extremely unlikely. But with tracing GC you’re often wasting 4-5x right from the start. Maybe it’s not called fragmentation, but the room needed for the GC to run efficiently is also waste. Plus all the headers in the objects to keep the marking flags also addup.
