[How Two GC Improvements Made Shopify's Storefronts 8% Faster](https://railsatscale.com/2023-08-08-two-garbage-collection-improvements-made-our-storefronts-8-faster/) — Shopify famously runs Ruby and Rails at a mind-boggling scale, so any improvements make a real impact to their bottom line. They've found two new such improvements that have reduced their response times by 8% _and_ will be released as part of Ruby 3.3, meaning we'll all benefit.
