A GC-Friendly Go Interning Cache
Go 1.20 is adding an interning cache for reused certificates. The entries are reference-counted with the help of the garbage collector and finalizers.

In #Golang 1.20 the Go team introduced an experimental new method of memory management called Go arenas.
In this blog post we show how we combined continuous profiling with memory arenas to improve performance of one of our cloud services by ~8% !
