And I also like the fact that GC in 2.1 no longer takes 50-60% of execution time. Usually it's more like 30-40% now.

Rails, as any tool, has its limits. When you're doing things at Twitter's scale, you need other tools.

Ruby 2.1 has a very important property: GC scales linearly with the amount of memory allocated.
Before 2.1 GC performance increased polynomially. So, for example, processing 10k rows from the table could take 10 seconds, and 100k would never finish.
With 2.1 everything I do actually finishes :)
