Quirinus batches transactions to order them before execution, allowing replicas to run the same sequence. It uses deterministic concurrency control with speculative execution and transaction reordering to reduce coordination costs. In tests, unoptimized Quirinus reaches up to 6.2× Tiga’s peak sustainable throughput on TPC-C, but Quirinus leads on YCSB only without added cross-data-center delay. This comparison uses different deployment architectures.
