How does Scala support ultra-low latency trading system architecture?

Low-latency trading systems minimize GC, avoid allocation, and use highly optimized pipelines.

Scala-based trading systems are optimized for microsecond-level latency. Techniques include object pooling, off-heap memory, lock-free structures, and JVM tuning (ZGC, NUMA awareness). Functional abstractions are often avoided in hot paths. Data flows are designed as linear pipelines with minimal branching and allocations.
