2. Performance Characteristics

The performance of this configuration has been benchmarked using several industry-standard tools and real-world containerized applications.

CPU Performance: Using the SPEC CPU 2017 benchmarks, the dual Intel Xeon Gold 6348 processors achieved an average score of 150 (base) and 220 (peak) per core. These scores indicate excellent performance for computationally intensive containerized workloads. See CPU Benchmarking for further details.

Memory Performance: Memory bandwidth was measured using STREAM benchmark, resulting in approximately 100 GB/s. This high bandwidth is critical for supporting a large number of containers and their associated memory requirements. See Memory Performance Analysis for detailed results.

Storage Performance: The RAID 10 NVMe storage array achieved sustained read/write speeds of 6 GB/s and 5 GB/s respectively, with an IOPS of over 800,000. This performance is essential for fast container image pulls and data persistence. See NVMe Storage Performance for more in-depth analysis.

Container Density: Using Docker Swarm, we were able to successfully deploy and run over 200 containers on this server without significant performance degradation. The actual number of containers depends on the resource requirements of each container. See Container Orchestration for more information.

Real-World Application Performance:

  • **Web Application (NGINX):** The server was able to handle over 50,000 requests per second with an average response time of 2ms, running NGINX in Docker containers.
  • **Database (PostgreSQL):** A containerized PostgreSQL database achieved a transaction rate of 10,000 TPS with a latency of 5ms.
  • **Microservices Architecture:** A complex microservices application consisting of 50 individual services deployed in containers demonstrated excellent scalability and responsiveness. See Microservices Deployment for best practices.
