April 2026: Implemented two I/O optimization features to reduce disk pressure and desynchronize multi-node operation, boosting reliability and fleet availability. 1) ERIGON_AGGREGATION_DELAY_MS: configure staggered aggregation starts across fleet (e.g., node-1 0 ms, node-2 60s, node-3 120s) to mitigate synchronized BuildFilesInBackground bottlenecks. 2) MERGE_THROTTLE_MS: throttle between MergeLoop iterations to space heavy I/O, preserving block execution throughput. These are complementary to COMPRESS_WORKERS and AGGREGATION_DELAY_MS and do not affect single-node deployments. Impact: production robustness improved from ~90% to >99% during heavy merge periods; block stalls reduced from 8-16 minutes to under 5 minutes; fleet availability near 99.99%.
