> David Chase: Struct packing/reordering is a mechanical thing humans shouldn’t be doing. If we had been doing this with protobufs, we’d have huge savings. 3% RAM footprint, ~20% GC cache traffic. We may end up doing GopherPen and being able to reorder struct fields eliminates a lot of the RAM footprint expense.

5x Slower than Go? Optimizing Rust Protobuf Decoding Performance
