A deep dive into MongoDB’s transaction model in WiredTiger: MVCC, snapshot isolation, update chains, and how it contrasts with lock-free hazard pointer and skip list concurrency in memory.
How MongoDB's WiredTiger storage engine achieves lock-free reads and writes using hazard pointers, skip lists, and atomic CAS operations.
More threads should mean more performance — but in Node.js, increasing UV_THREADPOOL_SIZE can actually reduce throughput. Here's why.
Worker threads can boost Node.js performance — or quietly destroy it. Learn when to use them, and when they make things worse.
A deep dive into isolation models in Node.js: when to use Worker Threads vs Child Processes, and the hidden costs that impact performance at scale.
How libuv's tiny threadpool can quietly throttle your Node.js APIs — and why scaling it blindly can make things worse.
Deep dive into Node.js microtasks, process.nextTick, and Promises — and how they secretly control execution order and can block your system.
Most engineers misunderstand the Node.js event loop. It doesn’t run async work—it schedules callbacks. This deep dive explains what really happens under the hood.
Most engineers think Node.js is single-threaded. It isn’t. This misunderstanding leads to poor system design, hidden bottlenecks, and scalability failures.
