Klara’s Expert Perspective on OpenZFS in 2026 and What to Expect Next
How will OpenZFS evolve in 2026? Klara’s experts outline their predictions across hardware, system design, and reliability. Read on for a grounded look at what to expect.
ZFS Performance Tuning in the Real World: ARC, L2ARC, and SLOG
Careless tuning in production can hurt stability and performance. This article explores ARC, L2ARC, and SLOG — when to tune, and the risks of overdoing it.
Optimizing ZFS for High-Throughput Storage Workloads
ZFS is more than just reliable—it can be fast. This article breaks down how to optimize ZFS for high-throughput storage workloads using ARC, prefetch, metadata vdevs, DirectIO, and tuning parameters to unlock real performance gains.
Customizing the FreeBSD Kernel
Understanding how to customize the build of the FreeBSD kernel and its loadable modules is an invaluable process for making custom additions or tuning the kernel build for a specific piece of hardware. Read our guide for useful examples and tips about kernel config file format and configuration, kernel module Makefiles and building out-of-tree modules.
Exploring Swap on FreeBSD
Answer burning FreeBSD memory questions like when to use swap space and how, but also kernel reactions to the shortages of free memory. Check out our 2021 guide to using swap space in FreeBSD.
OpenZFS: All About the Cache Vdev or L2ARC
The cache vdev, better known as “L2ARC” is one of the well-known support vdev classes under OpenZFS. But did you know it is not an ARC at all? Joins us in the journey to discover L2ARC, and learn about L2ARC feed rates, how it receives data, or when you should use it.
