June 2025 monthly summary for Shopify/grpc: Focused on stabilizing the benchmark workflow. No new features delivered this period; major action was a targeted bug fix to restore benchmark stability. Reverted the cluster name change in the gcloud command for psm benchmarks, returning from 'benchmarks-prod2' to 'psm-benchmarks-performance' to fix broken benchmarks and ensure reliable benchmark results. This work reduced false failures in the benchmarking pipeline and preserved the integrity of performance measurements.

January 2025 (2025-01) monthly summary for Shopify/grpc: Delivered reliability improvements to GKE performance benchmarks by correcting script issues that affected benchmark reporting and test filtering. The changes ensure benchmarks run with correct test disabling and precise scenario exclusions, resulting in more accurate performance results and reduced false positives/negatives. This work focused on ensuring measurement integrity and alignment with configuration output (scenario_config.py).

December 2024 monthly summary for Shopify/grpc focusing on improving CI reliability and benchmark stability across 8-core environments. Implemented a dynamic test filtering mechanism to selectively disable problematic benchmarks, ensuring green test suites and faster PR feedback loops. Key targeted fix: skip the flaky benchmark cpp_protobuf_async_client_unary_1channel_64wide_128breq_8mbresp_insecure on 8-core node pools, preventing flaky runs in CI.

November 2024 performance/CI monthly summary for Shopify/grpc. This period delivered two high-impact changes in the CI/perf workflow, restoring and aligning benchmarks with current infrastructure. Re-enabled OSS benchmarks for dotnet in CI, and migrated PSM benchmarks to Artifact Registry, strengthening the reliability and relevance of performance data across languages and image storage. Key outcomes: restored .NET benchmarking visibility in OSS benchmarks; updated image references to Artifact Registry for PSM benchmarks; improved CI stability and throughput for performance tests; better alignment with infrastructure changes and artifact management.
