software performance 4
- Relying on AI to replace performance engineers reduces an organization's overall technical expertise over time.
- Computer hardware performance depends on hardware, software, and tuning together, not hardware alone.

What Brendan Gregg says most about
data centers 3
- AI datacenter growth makes performance engineering critical for saving the planet, not just cutting costs.
- eBPF, Ftrace, and hardware performance counters are proven tools for finding datacenter performance wins.
developer tools 3
- Monitoring tools that do periodic work can themselves cause the latency outliers they were installed to diagnose.
- Major Linux distributions are increasingly shipping system libraries with frame pointers enabled by default
benchmarks 2
- Fair hardware benchmarks must use the best software and tuning for each hardware option, not hardware specs alone.
- A performance test without an explanation of its limiting factor should be treated as unanalyzed and possibly bogus.
management 2
- Giving a vendor brutally honest feedback helps the vendor and the customer's own company more than polite praise given out of fear
- Giving local staff authority over more-qualified remote workers reduces a company's competitiveness
remote work 2
- Giving local staff authority over more-qualified remote workers reduces a company's competitiveness
- Remote workers are often passed over for opportunities in favor of less-qualified local colleagues
semiconductors 2
- Customers who give hardware vendors firm, tough feedback accomplish more with them
- NVIDIA's Nsight Graphics GPU flame graphs are shallow and cumbersome to use compared to full-stack profiling tools
