Worked on performance and reliability improvements for the n0-computer/iroh repository, focusing on Rust-based benchmarking and network programming. Enhanced the DNS write benchmark by isolating the write loop, moving setup outside the measured duration, and generating distinct signed packets, which improved throughput reporting and enabled more accurate performance optimization. Addressed a fairness issue in the receive scheduler by storing an incremented receive counter and reversing polling order every other poll, ensuring even distribution across two custom transport lanes. Added integration-style unit tests to validate these changes, demonstrating a methodical approach to quality and collaboration through self-review and co-authored pull requests.
July 2026 performance and reliability improvements for n0-computer/iroh. Delivered two major capabilities with concrete business value and measurable technical impact. DNS Write Benchmark Measurement Enhancement refines benchmarking to isolate the DNS write path, reducing setup noise and improving throughput reporting; Receive Scheduler Fairness Bug Fix ensures even polling across two transport lanes and adds validation through tests. These changes enable targeted optimizations and more predictable production behavior. Notable changes include: (1) DNS write benchmark now measures only the write loop, moves setup outside measured duration, switches to Criterion iter_custom, and generates distinct signed packets for the measured batch, improving dns_server_writes throughput reporting (commit 9541a6d1357fccc33123f0c4736a71493ef9aa3b); (2) Receive scheduler fairness now stores the incremented receive counter and reverses polling order every other poll, with an integration-style unit test confirming even distribution across two custom transport lanes (commit 8e7819a909dbb0001a2c0057bac6cc4a0a5e14a6).
