ZJIT now integrates the garbage collector’s fast allocation path directly into JIT-generated code. That removes per-allocation function calls and lets common allocations run like a bump-pointer allocator, improving allocation performance.

Originally appeared on Rails at Scale . It’s been 8 years since the first just-in-time compiler was introduced in Ruby. However, throughout this time, the garbage collector has been a black box to the JIT compilers. This meant that JIT compilers were not able to optimize any object allocations and instead had to perfor
Originally appeared on Ruby Weekly . #​815 — September 3, 2026 Read on the Web Ruby Weekly ZJIT 🤝 GC: Inlining GC Fastpath in ZJIT — JIT compilation first came to CRuby eight years ago, but the garbage collector has remained opaque to CRuby's JITs, with every allocation requiring a function call. Now, ZJIT can
For decades, software development has been polarized into two distinct camps when it comes to memory management. On one side, you have languages with Garbage Collection (GC) like Java, Go, and C#, which offer safety and ease of use at the cost of unpredictable runtime pauses and higher memory overhead. On the other sid
Originally appeared on Josh Software . Most Go developers know how to write efficient Go code. But very few know what happens to that code after go build. Consider: How many function calls happen here? The obvious answer is one. But the real answer may be zero. The Go compiler can inline add, turning the call conceptua
Обычная системная куча обязана предполагать худшее: что в неё в любой момент постучатся из десятка параллельных потоков. Отсюда неизбежные блокировки, атомарные операции и накладные расходы. Но в GUI-приложениях на WinUI 3 этого сценария просто не бывает — все контролы и элементы разметки создаются и умирают строго в о
TL;DR — Mark an async fn with @rpc and call it from a .fitzv component as if it were local : let u = get_user(42).await? . The compiler generates both halves from that one declaration — a POST /__rpc/get_user endpoint on the server (which can touch the DB, auth, secrets) and a fetch -based stub on the client — with the
