The USE Method: SmartOS Performance Checklist
The USE Method provides a strategy for performing a complete check of system health, identifying common bottlenecks and errors. For each system resource, metrics for utilization, saturation and errors are identified and checked. Any issues discovered are then investigated using further strategies. In this post, I’ll provide an example of a USE-based metric list for [...]

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 [...]

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 [...]

The USE Method
A serious performance issue arises, and you suspect it’s caused by the server. What do you check first? Back when I was teaching operating system performance, I wanted a methodology my students could follow to find common issues quickly, without overlooking important areas. Like an emergency checklist in a flight manual, it would be something [...]
