Performance & Speed

Parallel Processing

Rather than running IPv4 and IPv6 tests sequentially, we initiate both connections simultaneously. This means the total test time is determined by the slower of the two connections, not their sum.

Edge Computing

Our diagnostic endpoints are deployed globally using a content delivery network approach. This ensures that regardless of where you are in the world, you're connecting to a server that's geographically close to you.

• 15+ strategic locations across 5 continents
• Anycast routing for automatic closest server selection
• Sub-50ms response times from anywhere on Earth
• Automatic failover between locations

Minimal Processing Overhead

Our servers are optimized for lightweight processing. The diagnostic information is extracted directly from network headers without any complex computation or database queries.

• Header extraction in microseconds
• No database queries for test processing
• All data served from memory
• HTTP/2 and compression enabled by default

Network Stack Optimization

Our servers run on a highly tuned Linux kernel with optimizations specifically for network diagnostic workloads:

• TCP buffer tuning for minimal latency
• Kernel bypass techniques for direct packet processing
• Pre-warmed connection pools for instant response
• Custom HTTP handlers with zero unnecessary overhead

Protocol-Level Efficiency

We leverage modern web protocols to minimize round trips and maximize efficiency:

• HTTP/2 multiplexing for concurrent requests
• Server-push for critical diagnostic headers
• Brotli compression for minimal payload sizes
• TLS 1.3 with 0-RTT for faster secure connections

Resource Management

Our infrastructure automatically scales to meet demand while maintaining consistent performance:

• Auto-scaling groups respond to traffic spikes in seconds
• Load balancing with health checks every 5 seconds
• CPU and memory limits prevent resource contention
• Automatic garbage collection tuning for latency-sensitive workloads
