## Perf

### 2026-05-14

- BAL optimistic merkleization: synthesize state deltas from the input Block Access List pre-execution and merkleize in parallel with the EVM on the `engine_newPayload` validation path. Includes a parallel state-trie pre-warm and per-account hashed-key-sorted storage inserts to keep the trie node arena hot for Stage B/C [#6655](https://github.com/lambdaclass/ethrex/pull/6655)

### 2026-04-27

- Reduce peak disk usage during snap sync by moving SST files into the temp DB instead of copying [#6532](https://github.com/lambdaclass/ethrex/pull/6532)
