quasarBuilding a Concurrent Echo Server with Crystal Fibers
Learn how Crystal’s lightweight fibers let you write concurrent network code that looks synchronous while staying on a single OS thread.
crystalChoosing Concurrency Patterns in Crystal: Fibers, Channels, and When to Escape the Scheduler
A decision guide for structuring concurrency in Crystal: compare pure fiber/CSP, supervised worker pools, thread bridges, and process isolation with a concrete worker-pool implementation and validation checklist.
Scaling HTTP Services with Crystal Fibers: When Cooperative Concurrency Wins
Learn how Crystal’s lightweight fibers let you handle tens of thousands of requests per second with minimal overhead, and see a concrete example that compares fiber‑based and thread‑per‑request servers.
Implementing Non-Blocking I/O with the Ruby Fiber Scheduler
Learn how to use Ruby's Fiber Scheduler to handle thousands of concurrent I/O operations on a single thread, reducing memory overhead and avoiding thread exhaustion.
rubyDesigning Concurrent I/O Services with Crystal Fibers and Channels
Learn how to implement a high-concurrency I/O service using Crystal's cooperative fibers and channels, including strategies to avoid scheduler stalls and memory leaks.
Crystal Fibers in Practice: Building a High-Concurrency Echo Server Without Callback Hell
Crystal's fibers let you write sequential-looking network code that scales to thousands of concurrent connections. Here's how the scheduler works, with a working echo server and channel-based broadcast example.
Crystal Fibers and Channels: Concurrency Without the Mutex Anxiety
Crystal's fibers and channels give you typed, backpressure-aware concurrency that reads like sequential code. Here's how the model works, a worker-pool example, and the pitfalls to avoid.
Structuring I/O-Heavy Workers in Crystal with Typed Channels and Fibers
Crystal's typed channels and fibers make I/O-heavy worker pools read like plain blocking code — but fibers aren't threads. A worked example, backpressure notes, and the parallelism caveat.
