Recent database benchmarks conducted by United Software Associates and Avalon Consulting, LLC highlight contrasting approaches in evaluating the performance of Couchbase and MongoDB. Avalon Consulting provided comprehensive documentation of their testing configurations, including the results of all tests, which ensures transparency and repeatability. In contrast, United Software Associates' benchmark lacked detailed configuration information such as the number of nodes, replica configurations, and other critical settings, raising questions about the credibility and reproducibility of their results. The benchmarks also revealed performance differences, with Avalon documenting superior throughput and latency metrics for Couchbase compared to MongoDB. The discussion emphasizes the importance of transparent and thorough documentation in benchmarks to avoid potential manipulation of configurations and to ensure fair comparisons.
