Python's Global Interpreter Lock or GIL, in simple words, is a mutex (or a lock) that allows only one thread to hold the control of the Python interpreter at any one time. In this article you'll learn how the GIL affects the performance of your Python pr
Express is asynchronous and single-threaded. It has an MVC (Model–View–Controller) like structure. Express has many robust APIs that make routing easy. In the process of learning Express.js, so far, we have seen ‘What is Express js? its core features, and why we should use it. Movin...
"Single-threaded" means that we open a single connection and measure the speeds from that. "Multi-threaded" means that we're using multiple connections - usually anywhere from 3 to 8 - at the same time, and measure the total speed across them all. What does single thread mean? noun. co...
