The Brief
What you'll do, and what you'll demonstrate.
Reduce a programmatic-ad-auction service's p99 from 78ms to under 25ms by attacking the top 4 tail-latency contributors identified through eBPF profiling.
Earning criteria — what you'll demonstrate
- Use bcc-tools + eBPF to profile tail-latency specifically
- Distinguish GC, lock-contention, page-fault, and NUMA-related tails
- Validate fixes in isolation to attribute speedup honestly
- Run a peak-load test that confirms p99 without p50 regression
