Ruby 2.1's GC is worlds faster, for most applications-- especially with a minor amount of tuning. I saw GC time drop from 20ms to under 5ms (using new relic). Memory usage until GC has gone up a bit though.

I can only hope, and have good reason to after 2.1, that future improvements are so good.

... Ruby just gets better by the year, I love it!
