Solana Block Capacity Surges 66% Yet Popular Account Bottlenecks Persist

Solana raised block CU limit by 66.7% to 100M, lowering single-account occupancy to 12%. However, the 12M CU write cap for identical accounts remains, leaving high-volume congestion unresolved.

Woofun AI reports that Solana elevated its block computation unit ceiling from 60 million to 100 million on July 29, marking a 66.7% expansion. This modification allocates additional parallel processing bandwidth for independent transactions, decreasing the block occupancy share of a single popular account from 20% to 12%. Nevertheless, the per-block computation threshold for writing to the same account stays fixed at 12 million CU, and the incremental data cap remains at 100 MB. Consequently, congestion issues for high-traffic accounts, such as major DEXs or liquidation contracts, remain unaddressed. Officials have not released comparative metrics regarding transaction confirmation rates, fees, block propagation, or replay performance following the upgrade.
