Once MCP sessions are created, uncomment the workload execution code. + +3. **Parallel Optimization**: User creation is staggered by 2 seconds. This could be optimized based on server capacity. + +4. **Error Recovery**: If a user fails to authenticate, it's removed from the pool but the benchmark continues.
