FreeBSD History – Understanding the Origins of DTrace

history of freebsd dtrace

DTraceis a powerful tool for system administrators to diagnosis system issues without unduly impacting performance. DTrace became part of FreeBSD with the release of FreeBSD 7.1 in 2009—two years before Oracle began porting DTrace, and nine years before Oracle eventually solved the inherent CDDL vs GPL license conflict.

FreeBSD vs. Linux – Tracing and Troubleshooting

When troubleshooting a Linux or FreeBSD system, you need to be able to probe the system to find answers as to why it is behaving in a particular way. In this article, we’ll provide an overview of some of the basic tools and introduce the FreeBSD equivalents of common Linux tracing and troubleshooting tools.

The more we automate, the more we can save time and boost our productivity to higher levels. In this article we plan on looking at how to build more human-readable outputs in FreeBSD by leveraging tools like libxo to drive better output for automation APIs.

OpenZFS – Data Security vs. Integrity

Linux vs. FreeBSD - Package Management

The popularity of package managers permeates all Unix distributions. Yet there are subtle differences in the approach that Linux vs. FreeBSD take in handling packages. How does Linux compare to FreeBSD’s way of managing packages? We have identified key points to consider in the software lifecycle management of both in the article below.

FreeBSD vs. Linux – Key Differences Between FreeBSD and Linux Networking

FreeBSD vs. Linux - Networking

The question isn’t as much “Should I choose FreeBSD or Linux”, the question should be “Which OS fits my needs best?”. In our most recent comparison article, we go over the two implementations of the networking stack and look at how Linux implements networking and how FreeBSD fares in most cases.

The Role of Operating Systems in Iot

The number of Internet of Things devices both in our homes and in the world has exploded in the last few years. Smart IoT devices can now replace everything from the humble light switch all expand all the way to smart lawnmowers, All of these devices are driven by an Operating System of some sort.

FreeBSD vs. Linux – Virtualization Showdown with bhyve and KVM

Linux vs. freebsd - bhyve vs kvm

The bhyve hypervisor makes it easy to run reliable, high-performance virtual machines on a FreeBSD host system. In this article, we test the performance of virtual machines running Windows, Linux, and FreeBSD itself under bhyve—and we compare and contrast with performance of the same virtual machines running under Linux’s well-known KVM hypervisor. Understanding the pros and cons of each hypervisor helps you make confident, informed decisions when deciding how to set up your virtualization hosts.
