Node.js — libuv status report
We announced back in July that with Microsoft's support Joyent would be porting Node to Windows. This effort is ongoing but I thought it would be nice to make a status report post about the new platform library libuv which has resulted from porting Node to Windows. libuv's purpose is to abstract platform-dependent code in Node into one place where it can be tested for correctness and performance b

ApacheBench was used to run the benchmarks with the following
The reasons I stopped using libuv for H2O
Libuv is a great cross-platform library that abstracts various types of I/O by using callbacks. So when I started writing H2O - a high-performance HTTP server / library implementation with support for HTTP1, HTTP2 and websocket, using libuv seemed like a good idea. But recently, I have stopped using it for sereval reasons. This blog post explains them. â– No Support for TLS Although libuv provides a

We're sad to lose the benefit of his continued hard work and expertise, and extremely grateful for what he has added to Node.js and libuv over the years.

Threads — An Introduction to libuv
Threads¶ Wait a minute? Why are we on threads? Aren’t event loops supposed to be the way to do web-scale programming? Well... no. Threads are still the medium in which processors do their jobs. Threads are therefore mighty useful sometimes, even though you might have to wade through various synchronization primitives. Threads are used internally to fake the asynchronous nature of all of the system
Asynchronous I/O in Windows for Unix Programmers
Asynchronous I/O in Windows for Unix Programmers Ryan Dahl 2011-04-26 This document was an attempt at understanding how best to port Node.js to Windows. The result of the port was the library libuv, which (among other things) provides a unified interface for asynchronous networking on the three big operating systems: Linux, OSX, and Windows. This document assumes you are familiar with how non-bloc
