Latency is one of those invisible performance killers — even systems that work can feel slow, fragile, or unresponsive because of micro-delays that accumulate. That’s exactly what Pekka Enberg tackles in his new book, Latency, now available through Manning’s Early Access Program (MEAP).

From first principles through hands-on techniques, Latency shows you how to spot, understand, and fix unwanted delay in software and infrastructure. It doesn’t treat latency as an afterthought — it treats it as a first-class concern across layers (OS, network, application, data).

Here’s what you’ll get out of this book:

• A clear distinction between latency vs. bandwidth, and why bandwidth optimizations often miss the real issue

• Models (Little’s Law, Amdahl’s Law) and measurement strategies to quantify latency and its sources

• Techniques to optimize at every level: colocation, replication, partitioning, caching

• Ways to speed internal logic: algorithmic improvements, memory tuning, lock-free concurrency

• Methods to hide latency when you can’t eliminate it: asynchronous processing, speculative execution, prefetching

One thing I especially liked in early previews is the code repository that comes with the book — you can experiment with reference implementations to better internalize the concepts. GitHub

If your goal is to build fast, responsive, high-quality systems — especially those that operate over networks, in distributed environments, or on tight SLAs — this is a resource that’ll help you put theory into practice.
