Latency Critical Systems

Built for anyone shipping realtime dashboards, market data feeds, streaming agents, or execution infrastructure where p95 latency and freshness actually matter. It walks you through splitting metrics properly (p50/p95/p99, throughput, queue depth, cache hit rate), mapping the hot path from source event to browser render, and optimizing in the right order: kill round trips, cache with freshness metadata, batch writes, move compute closer to data. The verification section is solid, especially the guardrails around not hiding stale data behind fast caches and not claiming millisecond behavior without measurement. It won't help you write trading algorithms, but it will help you measure and fix the infrastructure around them.
