A claim is making the rounds: Sui’s public mainnet hit over 6 million transactions per second. That’s a number worth pausing on, because context is doing a lot of heavy lifting here.

The 6M+ TPS figure has circulated on social media, but verified benchmarks from the Sui Network itself and credible on-chain data tell a more complicated story.

What the benchmarks actually show

Sui’s mainnet launched on May 3, 2023. Since then, its real-world throughput has averaged in the low hundreds of TPS daily, with occasional spikes approaching 900 to 1,000 TPS under peak load conditions.

A December 2025 benchmark conducted on the mainnet recorded approximately 103,435 certificate-per-second (CPS) performance under controlled testing conditions.
