Notes

  • Latencies reported in seconds (converted from milliseconds)
  • Values shown as mean ± standard deviation across multiple seeds
  • Throughput = commits per second during steady-state window
  • Success rate = percentage of transactions that committed successfully
  • Mean retries = average number of retry attempts per committed transaction
