PROFILE

David Veszelovszki

Veszelovszki developed and enhanced gateway performance benchmarking features for the sourcegraph/src-cli repository, focusing on end-to-end latency measurement and reporting for Cody Gateway endpoints. Using Go, he implemented CLI commands that benchmarked both HTTP and WebSocket endpoints, provided detailed latency statistics, and supported CSV export for external analysis. He addressed resource management and pointer safety to ensure robust, leak-free benchmarking runs, and improved CI reliability through careful error handling. Additionally, Veszelovszki contributed Rust documentation updates to rust-lang/this-week-in-rust, clarifying the performance benefits of mtp-rs over libmtp and streamlining onboarding for Rust developers through improved technical messaging.

November 2024: Delivered a gateway performance benchmarking capability for src-cli, enabling performance visibility of Cody Gateway endpoints from the command line. The new 'src gateway benchmark' command runs end-to-end benchmarks, reporting average, median, and percentile latency, with an option to export results to CSV for easy sharing with stakeholders. This work was implemented as a focused feature in sourcegraph/src-cli and is traced by the commit that adds the command (177b25b230125397190810d657d49a75c763272f) under the feature tag: feat/gateway: Add `src gateway benchmark` command (#1124).
