Plurrrr

I came across a post on Cloudflare Blog where the author was describing his experience on tackling the issue of removing duplicate lines from a large file. The following text is a comment sharing my experience and alternative approach to the task that yields performance results similar to the author’s but without going down the route of coding in C. Funnily, this comment was rejected by Cloudflare Blog moderators. Thus, not to lose a couple of hour’s worth of work, I am putting it out here.

KVM is a virtualization technology that comes with the Linux kernel. In other words, it allows you to run multiple virtual machines (VMs) on a single Linux VM host. VMs in this case are known as guests. If you ever used QEMU or VirtualBox on Linux - you know what KVM is capable of.

But how does it work under the hood?
