How does Scala handle latency-sensitive system design?

Scala reduces latency via minimal allocation, async IO, and tuned JVM execution.

Latency-sensitive systems in Scala rely on non-blocking IO (Netty, Akka HTTP), avoiding garbage creation in hot paths, and using preallocated structures. JVM tuning (G1/ZGC) reduces pause times. Functional pipelines are carefully designed to avoid intermediate collections. Libraries like ZIO provide fiber-based concurrency for efficient scheduling.
