I don't know if a slight performance increase is going to sell anyone on ruby but I'm glad they're making incremental improvements on things. Being overly concerned about performance is almost always premature optimization, and ruby is more than fast enough for everything I've ever asked of it (including the binding glue between our redis DNS record storage and PowerDNS, where the entire stack serves half a billion queries a month across 14 tiny VPSes without even a blip on htop). I probably could have just used ruby instead of PowerDNS but it's generally not great to roll-your-own on public facing encryption, HTTP, DNS, etc. It wasn't really a performance consideration for me.
The recent irony of the web is anyone that implemented a web app with "slow" ruby and backend rendering now has the fastest page loads compared to bloated front-end web apps backed by actually slow eventually consistent databases that take seconds to load even the tiniest bits of information. I see the spinner GIF far too often while doing menial things on the "modern" web.
