zfsday: ZFS Performance Analysis and Tools
At zfsday 2012, I gave a talk on ZFS performance analysis and tools, discussing the role of old and new observability tools for investigating ZFS, including many based on DTrace. This was a fun talk – probably my best so far – spanning performance analysis from the application level down through the kernel and to [...]

USENIX LISA 2012: Performance Analysis Methodology
At USENIX LISA 2012, I gave a talk titled Performance Analysis Methodology. This covered ten performance analysis anti-methodologies and methodologies, including the USE Method. I wrote about these in the ACMQ article Thinking Methodically about Performance, which is worth reading for more detail. I’ve also posted USE Method-derived checklists for Solaris- and Linux-based systems. The [...]

USENIX LISA 2010: Visualizations for Performance Analysis
My USENIX LISA talk from 2010 is now available on youtube, also embedded below. The title is Visualizations for Performance Analysis (and more), and showed how the full distribution of data could be presented as a heat map. This is especially useful for latency analysis, as fast-path and slow-path differences can be studied, as well [...]

Surge 2012: Real-time in the real world
In September, I attended and spoke at the Surge’12 conference in Baltimore. I highly recommend it for anyone interested in performance. The theme with most talks was problems encountered at scale – and as is often the case – you can learn more from failure than success. Bryan and I gave a talk titled “Real-time [...]

FISL13: The USE Method
In July, Bryan Cantrill, Deirdré Straughan and I spoke at FISL, one of the world’s largest open software conferences, in Porto Alegre, Brazil. I had a great time. My talk introduced the USE Method: a simple strategy for performing a complete check of system performance health, identifying common bottlenecks and errors. This methodology can be [...]

Performance Analysis talk at SCALE10x
Last week I gave a talk at the Southern California Linux Expo (SCALE) titled “Performance Analysis: New Tools and Concepts from The Cloud”. There was a great turnout for my talk, which was videoed by Deirdré (video below). The conference was a lot of fun too. In my talk I presented six problems of performance [...]
