Node vs Bun: what are you seeing for P50 / P90 / P99 tail latency?
I'm comparing Bun and Node for server-side workloads and I'm particularly interested in tail latency, not just throughput.
For people running Bun and Node in production or serious benchmarks:
- What are you seeing for P50?
- P90 / P95?
- P99 / P99.9?
- Does Bun actually have better tail latency for your workload, or is the difference mostly in throughput?
I'm especially interested in HTTP servers and SSR, but database/API-heavy workloads are useful too.
If you have numbers, please include:
- Bun/Node version
- workload
- OS
- concurrency / request rate
- whether the load generator ran on the same machine
- P50/P95/P99 (and P99.9 if available)
I'm trying to understand whether differences in P99 are actually runtime-related or mostly caused by the workload/platform/benchmark methodology.
