Bio

I hate writing bios. From time to time, conference organizers, journalists, and publishers ask me for a bio of a certain length ("50-75 words, "around 100 words", etc.), and so I'll cache my most recent ones here. This page also has my interviews and upcoming talks.

Very Short

Industry expert in computing performance and eBPF. Solves hard problems. Makes things faster.

Brendan Gregg is an internationally renowned expert in computing performance. He is a senior performance engineer at Netflix, where he does large-scale computer performance design, evaluation, analysis, and tuning. Previously among the top performance experts at Sun Microsystems, he has delivered industry-leading performance for a variety of commercial products and enterprise environments. He has also created widely used tools, methodologies, and visualizations for performance analysis, including flame graphs. His tools are included in multiple operating systems and products, and are in use by companies worldwide. He pioneered eBPF as an observability technology, and leads the industry in its usage. His work has saved the industry over US$1B through performance improvements, and has been the basis for multiple startups.

He has authored hundreds of articles about systems performance and multiple technical books, including Systems Performance 2nd Edition (2021) and BPF Performance Tools (2019), both in the Addison-Wesley professional computing series. His prior books were on Solaris performance and DTrace, and were published by Prentice Hall. His books are recommended or required reading at major technology companies. He has also been an invited keynote speaker at technical conferences worldwide, and received the USENIX LISA Outstanding Achievement award.

He provides performance expertise for multiple company functions, including directing other teams, evaluating new technologies, and making individual contributions. He has extensive performance tuning experience for enterprise and small- to large-scale cloud computing environments, and root cause analysis of complex problems across the software stack and down to metal. He has worked with sales organizations to win and retain customers during proof of concepts and product support, including direct work with Fortune 500 companies, securing millions in company revenue. He represented Sun Microsystems and Netflix worldwide as a performance expert.

His creations include flame graphs and latency heat maps, the USE methodology, and advanced eBPF tracing tools to provide unique insights into system behavior. His prior work includes leading performance efforts for the world's first container-based cloud, and for the first ZFS storage appliance, in both cases delivering industry-leading performance. As a kernel engineer, he developed the ZFS L2ARC: A pioneering file system performance technology. He has also developed and delivered professional training courses on computer performance.
