... and 1-2% improvement in performance via the register allocator.

  In this day and age, that's a pretty large compiled code performance improvement from just one feature.

  If google has 10 million servers then a 2% improvement would be like freeing up 200,000 servers. That's a significant amount of value added!

    It usually makes more sense to think in terms of cores rather than servers, because server density has always been increasing :)

    If Google has 100 data centers they can sell 2 of them.

  Across the board improvements from changing register allocators is surprisingly difficult to get. Couple of percent sounds great. It's usually done heuristically in a fashion that scales badly with how many instructions you're considering at a time so it's really easy to overfit to today's benchmark.
