Solana Boosts Block Capacity by 66%, But Bottleneck Remains

Solana's block capacity has increased by 66% after the network raised its per-block compute ceiling from 60 million to 100 million compute units (CUs) on July 29. This change gives unrelated transactions more room, but leaves the separate cap governing Solana's busiest accounts intact.

The new limit expands parallel headroom for transactions touching unrelated accounts, allowing them to use the additional 40 million CUs. However, this does not give a congested market more capacity, as many trades still compete within the 12 million-CU allowance when targeting the same account.

According to Solana's fee documentation, an optional prioritization fee depends on a transaction's requested CU limit and CU price, raising its likelihood of being scheduled. The higher block ceiling alone does not show that priority fees fell for transactions targeting the same hot state.
