Fourteen years after the launch of Go, there is much to think about. With the benefit of hindsight, this talk explores some of the lessons learned from Go's progress so far: not just the things that went well but also the things that could have been done…

When running on baremetal, however, we found two key limitations of the Go runtime so far: Systems with a lot of RAM can have a lot of allocations, prompting the Go Garbage Collector to aggressively steal CPU. 2. Applications performing hundreds of thousands…

Split from #31908 (comment) and full write-up at https://jazco.dev/2024/01/10/golang-and-epoll/. tl;dr is that a program on a 192 core machine with >2500 sockets and with >1k becoming ready a...

So, there's this function. It's called a lot. More importantly, all those calls are on the critical path of a key user interaction. Let's talk about making it fast.

In this talk, we introduce balanced GC, which allows bump allocation for small pointerless objects in per-goroutine allocation buffers and uses a copying GC to manage that memory. Balanced GC can significantly accelerate object allocation and improve the…
