Async I/O Benchmark Decision Studio
Create a developer tool that runs workload-specific comparisons between epoll and io_uring, then explains results in business-relevant terms like throughput, latency, CPU efficiency, and operational risk. The value is not just running benchmarks, but interpreting when higher CPU is healthy versus wasteful.
Pourquoi c'est important
You changed an async backend and saw CPU numbers move, but that did not answer whether the system got better. In performance work, visible resource usage can go up while actual throughput or tail latency improves, and teams often misread that signal. Existing benchmarks and blog posts tend to compare idealized cases, while your service has its own request shape, blocking behavior, and kernel configuration. You need a tool that runs realistic tests, compares event models on your own workload, and explains whether a change is a win, a wash, or a hidden regression. Without that, you waste engineering cycles debating graphs instead of shipping reliable improvements.

Périmètre MVP · 1–2 semaines
- Build a CLI that runs a minimal epoll versus io_uring comparison harness
- Support one sample workload template for HTTP echo or reverse proxy traffic
- Generate a local HTML report with throughput, latency, and CPU graphs
- Add a rules layer that flags when CPU rises but throughput also improves
- Recruit 10 early users from systems-programming communities for trial runs
- Add CI integration for scheduled regression checks on pull requests
- Support workload replay from captured request traces or synthetic profiles
- Implement baseline comparison across kernel versions and instance types
- Launch a hosted dashboard to store historical benchmark runs
- Publish 3 example case studies showing how to interpret conflicting metrics
Différenciation
Pourquoi cela pourrait échouer
Auto-contre-argument — le signal de confiance le plus important
- 1Users may see the tool as a benchmark wrapper rather than a must-have product if interpretation quality is weak.
- 2Accurate results require representative workloads, and many teams may not have clean test traffic to replay.
- 3Open-source benchmarking frameworks could undercut pricing unless the reporting layer is clearly superior.
Résumé des preuves
Comment l'IA a synthétisé cet aperçu — pas de citations textuelles
A large share of the discussion centered on how to interpret performance changes correctly. Multiple commenters stressed that CPU utilization alone is misleading and that real evaluation depends on throughput and integration details. That pattern suggests demand for a tool that not only runs experiments but explains the practical meaning of the outcomes for production systems.
