Real-World Performance
In real-world scenarios, the infrastructure currently supports approximately 50,000 concurrent users with an average bandwidth usage of 5Mbps per user. Peak usage during high-demand periods (e.g., school hours, national events) has been successfully sustained without significant performance degradation. Monitoring tools (see Server Monitoring Tools) are used to track key performance indicators (KPIs) and identify potential bottlenecks. Traffic analysis indicates that the majority of bandwidth is consumed by video streaming, social media, and web browsing. The firewall logs show a consistent rate of blocking malicious traffic, demonstrating the effectiveness of the security infrastructure. The load balancers distribute traffic evenly across available server resources, ensuring high availability and responsiveness.
Bottleneck Analysis
Current analysis indicates that the network interfaces are the primary potential bottleneck under extreme load. While the 100Gbps links provide ample bandwidth for current usage, future growth may require upgrading to 400Gbps or faster technologies. Storage performance, while adequate, could benefit from the addition of NVMe SSDs for caching frequently accessed data. Storage Tiering explores this concept.
