Open Source Systems Performance

There is an important and untold story about open source and systems performance, which I’m uniquely positioned to tell. I presented it at OSCON earlier this year, which was the perfect venue. My talk, Open Source Systems Performance, was a play in three acts: Act 1. Before Open Source Act 2. Open Source Act 3. [...]

Linux Performance Analysis and Tools

At the Southern California Linux Expo earlier this year (SCaLE 11x) I presented a talk on Linux Performance Analysis and Tools. It’s a great conference, and I was happy to be back. My talk provided an overview of over twenty performance tools, and I described the problems they solve. At the end of the talk, [...]

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 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 [...]

dtrace.conf 2012 videos

Last month was dtrace.conf 2012, the 2nd DTrace unconference. This is a meetup of DTrace practitioners and developers, where we discuss the latest uses, developments and future directions of the technology. It was great to see old friends of DTrace, and to put new faces to names. See the video list for the sessions, which, [...]

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 [...]

Breaking Down MySQL/Percona Query Latency With DTrace

In May I spoke at PerconaLive 2011 in New York, giving a talk titled “Breaking Down MySQL/Percona Query Latency With DTrace”. It was a great conference, and I’d recommend attending the next one if you get a chance. I also attended a number of the talks, and have also caught up on some via video [...]
