Reports claiming the Sui public mainnet hit over six million transactions per second are circulating. Verified data tells a different story.
Sui's mainnet launched in May 2023. Its daily real-world throughput averages in the low hundreds of TPS. Peaks under load approach one thousand TPS. A December 2025 benchmark under controlled conditions recorded roughly 103,435 certificates per second.
The six million TPS figure is more closely associated with testing of Solana's Firedancer client. No official Sui channel or credible third-party audit has confirmed that result on Sui's public mainnet.
Sui's technology, including its object-centric data model and the Mysticeti upgrade, shows genuine engineering ambition. The network competes for developers and liquidity against rivals like Solana, Aptos, and Ethereum Layer 2 networks.
Investors evaluating performance narratives should seek primary sources. Throughput claims not traced to official Sui benchmarks or named third-party audits remain unconfirmed. The gap between controlled test results and real-world demand highlights the importance of watching developer adoption, total value locked in Sui's DeFi ecosystem, and official network disclosures.
