Garbage Collection

The D programming language is an object-oriented, imperative, multi paradigm system programming language. D language originated as a re-engineering of C++, and D's design goals try combining the performance of compiled languages with the safety and expressive power of modern dynamic languages. Native D code is commonly as fast as equivalent C++ code while being shorter and memory-safe.

Benchmarks

This benchmark tests how fast a framework can perform concurrent HTTP requests, I/O operations, and JSON de/serialization.

MedianP99

Framework	Requests per second Indicates how many requests per second the framework can handle. (higher is better)	Latency Indicates how long it takes to process a request. (lower is better)	Stability Indicates how stable the framework is under load: median / P99 latency (higher is better)	Memory Indicates how much memory (RAM) the framework uses. (lower is better)
