2. Performance Characteristics

This configuration is designed for high throughput and low latency data processing. Performance testing was conducted under simulated load representing 5,000 containers, each generating a consistent stream of metrics and logs.

  • **CPU Utilization:** Under peak load, average CPU utilization is maintained at approximately 60-70%. The dual CPUs provide sufficient headroom for scaling.
  • **Memory Utilization:** With 512GB of RAM, memory utilization remains below 80%, even with the Prometheus time-series database fully populated. Caching plays a significant role in maintaining performance. Memory Management Techniques
  • **Disk I/O:** The RAID 10 configuration delivers consistent I/O performance, averaging 1.5 GB/s read and 1.2 GB/s write speeds during peak load. This ensures that metrics and logs are written to disk without bottlenecking. Disk I/O Performance
  • **Network Throughput:** The 25GbE NICs provide ample bandwidth for transferring monitoring data, achieving sustained throughput of over 20 Gbps.
  • **Prometheus Query Latency:** Average query latency for common metrics remains below 200ms, ensuring timely alerting and visualization. Prometheus Query Language (PromQL)
  • **Grafana Dashboard Load Time:** Dashboard load times consistently remain under 3 seconds, even with complex visualizations displaying data from numerous containers. Grafana Dashboard Design
  • **Log Ingestion Rate:** Loki/Tempo are capable of ingesting approximately 50,000 log lines per second without performance degradation. Log Ingestion Rate Optimization


    • Benchmark Results (Sysbench):**

| Benchmark | Score | |---|---| | CPU (Prime Numbers) | 285,000 | | Memory (Read) | 180,000 MB/s | | Memory (Write) | 165,000 MB/s | | Disk I/O (Sequential Read) | 1,450 MB/s | | Disk I/O (Sequential Write) | 1,180 MB/s |

These benchmarks were performed with a standard Sysbench configuration and are representative of the server's overall performance capabilities.
