Wow! This is potentially a real gain for us. We have a big in-house, monolithic Rails app. My initial experiment was encouraging. Boot time in development mode went from ~23sec to ~16sec, and I only enabled it for the main engine that comprises about 85% of our codebase so the real gains might be larger. Looking forward to seeing what it can do in production mode - our boot times there are horrendous and it's a big deal for things like cron jobs. Thank you to all those who worked on this.
