Ten Ways To Easily Improve Oracle Solaris ZFS Filesystem Performance

ZFS Performance

This is a long article, but I hope you'll still find it interesting to read. Let me know if you want me to break down future long articles into multiple parts instead.

One of the most frequently asked questions around ZFS is: "How can I improve ZFS performance?".

This is not to say that ZFS performance would be bad. ZFS can be a very fast file system. ZFS is mostly self-tuning and the inherent nature of the algorithms behind ZFS help you reach better performance than most RAID-controllers and RAID-boxes - but without the expensive "controller" part.

Most of the ZFS performance problems that I see are rooted in incorrect assumptions about the hardware, or just unrealistic expectations of the laws of physics.

So let's look at ten ways to easily improve ZFS performance that everyone can implement without being a ZFS expert.

OpenSolaris ZFS Deduplication: Everything You Need to Know

Since November 1st, 2009, when ZFS Deduplication was integrated into OpenSolaris, a lot has happened: We learned how it worked, people got to play with it, used it in production and it became part of the Oracle Sun Storage 7000 Unified Storage System.

Here's everything you need to know about ZFS Deduplication and a few links to help you dig deeper into the subject:

Home Server: RAID-GREED and Why Mirroring is Still Best

Disks in a circle. How cute.

After moving my blog to its new home and getting my hands dirty with Drupal, it's time to continue my series of blog articles about setting up a home server. Remember? We talked about home server requirements, then I presented to you my small and energy-efficient, still ECC-protected and powerful AMD-based home server. Now it's time to explore some different ZFS disk pool RAID strategies.
