New ELF Linker from the LLVM Project

December 1, 2015

We have been working hard for a few months now to rewrite the ELF support in lld, the LLVM linker. We are happy to announce that it has reached a significant milestone: it is now able to bootstrap LLVM, Clang, and itself and pass all tests on x86-64 Linux and FreeBSD with the speed expected of an LLVM project.

ELF is the standard file format for executables on Unix-like systems, such as Linux and BSDs. GNU ld and GNU gold are commonly used linkers for such systems today. In many use cases, the linker is a black box for which only speed matters. Depending on program size, linking a program takes from tens of milliseconds to more than a minute. We designed the new linker so that it runs as fast as possible.

Linux Performance Analysis in 60,000 Milliseconds

You login to a Linux server with a performance issue: what do you check in the first minute?

At Netflix we have a massive EC2 Linux cloud, and numerous performance analysis tools to monitor and investigate its performance. These include Atlas for cloud-wide monitoring, and Vector for on-demand instance analysis. While those tools help us solve most issues, we sometimes need to login to an instance and run some standard Linux performance tools.

In this post, the Netflix Performance Engineering team will show you the first 60 seconds of an optimized performance investigation at the command line, using standard Linux tools you should have available.

Docker is an interesting technology that over the past 2 years has gone from an idea, to being used by organizations all over the world to deploy applications. In today’s article I am going to cover how to get started with Docker by “Dockerizing” an existing application. The application in question is actually this very blog!

What is Docker

Before we dive into learning the basics of Docker let’s first understand what Docker is and why it is so popular. Docker, is an operating system container management tool that allows you to easily manage and deploy applications by making it easy to package them within operating system containers.
