Viral Claim of Sui Mainnet Hitting 6M+ TPS Doesn’t Hold Up, Data Shows

A claim that Sui’s public mainnet processed more than 6 million transactions per second has spread widely on social media, but the figure does not hold up against verified benchmarks, according to Crypto Briefing. The number appears to have originated from testing of Solana’s Firedancer client rather than any confirmed result on Sui’s network.

No official announcement from the Sui Network or report from credible outlets has confirmed a 6M+ TPS result on Sui’s public mainnet, Crypto Briefing reports. The discrepancy matters for investors who may weigh performance claims when assessing the Layer 1 network’s competitive position.

What the real benchmarks show

Sui’s mainnet launched on May 3, 2023, and its real-world throughput has since averaged in the low hundreds of transactions per second daily, with occasional spikes approaching 900 to 1,000 TPS under peak load, according to the report. A December 2025 benchmark run on the mainnet under controlled testing conditions recorded approximately 103,435 certificate-per-second performance, a different and more technical metric than raw TPS.

Historical testnet figures, cited by Crypto Briefing, are considerably higher than mainnet activity. Across various workloads run with 100 validators, Sui’s testnet benchmarks ranged from roughly 10,871 TPS at the low end to 297,000 TPS at peak, with time to finality around 480 milliseconds. Those numbers, however, reflect controlled test environments rather than live network conditions.

Why throughput claims keep circulating

Sui’s architecture does carry genuine technical ambition. The network uses an object-centric data model and has pursued consensus improvements through its Mysticeti upgrade, which targets lower latency, per Crypto Briefing.

Sui competes for developer attention and liquidity against Solana, Aptos, and a range of Ethereum Layer 2 networks. In that competitive environment, an inflated throughput headline can function as market positioning even when it is inaccurate, the outlet notes.

What investors should watch instead

Crypto Briefing advises that investors drawn to Sui because of performance narratives should first locate the primary source of any throughput claim. If a figure does not trace back to an official Sui benchmark or a named, verifiable third-party audit, it should be treated as unconfirmed.

The gap between Sui’s controlled test results, over 100,000 certificates per second, and its real-world mainnet peaks of roughly 1,000 TPS, suggests a network with unused capacity rather than one that has demonstrated demand at scale, according to the report. Developer adoption metrics, total value locked in Sui-native DeFi protocols, and official network performance disclosures are cited as the more meaningful indicators for tracking the chain’s progress.
