Has anyone using ruby 2.7?

Hi,

I've been wondering what's the adoption of ruby 2.7. Has anyone here migrated a production app to 2.7?

I've done some rudimentary tests on SaaSHub (development), and it's a touch slower in most cases. I am aware that there are some GC improvements. It could be the case that switching to 2.7 improves memory consumption on long running processes (puma, sidekiq, etc).

If you have any, what's your experience?

Thanks in advance.
