This document is a technical report detailing the performance testing conducted by CertiK on the Qubic mainnet. The engagement aimed to evaluate the network's capacity to handle high transaction volumes, assess throughput, measure response times and latency, analyze performance under sustained loads, and determine maximum transactions per second (TPS). The assessment was carried out between February 12 and April 1, 2025, using a specialized testing framework developed by CertiK. This framework included various testing methodologies such as single-instance stress tests, integrated stress tests, and stochastic random stress tests. Each test mode provided granular control over parameters like duration and load patterns. The report includes detailed logs and performance metrics, including average TPS, peak TPS, and transaction throughput metrics. The results of the tests are documented, providing insights into network stability and performance variance across different environments, specifically the Qubic testnet and mainnet.
