+# Async Runtimes Benchmarks 2025
+
+## Benchmark Evolution and Methodology
+
+### Purpose
+
+This benchmark aims to measure the memory footprint and performance characteristics of concurrent tasks across different programming language runtimes in 2025.
+
+### Benchmark Specification
+
+- Spawn N concurrent tasks (controlled by command-line argument)
+- Default task count: 100,000
+- Each task waits for 10 seconds
+- Program exits when all tasks complete
+
+## Improvements in 2025 Benchmark
+
+### Standardization Efforts
+
+1. **Consistent Task Implementation**
+   - Explicit task creation mechanism - 2024 previous implementations vary slightly in how they create and manage tasks. We should standardize.
+   - Standardized 10-second wait
+   - Detailed task result tracking
+   - Comprehensive error handling
+   - Detailed performance tracking
+
+2. **Language-Specific Enhancements**
+   - Python (asyncio):
+     - Explicit task creation with `asyncio.create_task()`
+     - Comprehensive error handling
+     - Detailed task result tracking
+
+   - Node.js:
+     - Promise-based task creation
+     - Error handling with `Promise.allSettled()`
+     - Detailed task duration tracking
+
+   - Go:
+     - Context-based timeout management
+     - Structured goroutine approach
+     - Error tracking and reporting
+
+   - Rust (Tokio):
+     - Detailed task tracking
+     - Cancellation support
+     - Comprehensive error handling
+
+   - Kotlin (Coroutines):
+     - TaskResult data class for comprehensive result tracking
+     - Kotlin coroutines for concurrent task management
+     - Detailed timing with Instant and Duration
+     - coroutineScope for structured concurrency
+     - awaitAll() for comprehensive task completion
+     - Flexible task count with default of 100,000
+     - Detailed result printing with task ID and duration
+
+   - C# (.NET Tasks):
+     - Introduced a record TaskResult for structured result tracking
+     - Used Task.Run() for concurrent task creation
+     - Implemented detailed timing with DateTime and TimeSpan
+     - Used ConcurrentBag for thread-safe result collection
+     - Comprehensive error handling
+     - Flexible task count with default of 100,000
+     - Optional result printing with task details
+
+   - Elixir (Processes):
+     - Created a custom struct for task result tracking
+     - Used Elixir's lightweight processes for concurrency
+     - Implemented detailed timing with system time
+     - Used spawn_link for process creation
+     - Message passing for result collection
+     - Flexible task count with default of 100,000
+     - Optional result printing with task ID and duration
+
+### Benchmarking Recommendations
+
+## Overarching Recommendations:
+
+- Standardize memory tracking across languages
+- Add detailed logging and tracing
+- Implement consistent performance metrics
+- Create a unified result collection and reporting mechanism
+- Add configuration for different benchmark scenarios
+
+1. **Consistent Environment**
+   - Use identical hardware
+   - Standardized OS and runtime versions
+   - Minimal background processes
+
+2. **Metrics Collection**
+   - Memory usage
+   - CPU utilization
+   - Task creation overhead
+   - Total execution time
+   - Garbage collection impact
+
+### Methodology Notes
+
+- Multiple iterations for statistical significance
+- Warm-up runs to stabilize runtime environments
+- Detailed logging of task performance
+
+### Future Improvements
+
+- Implement similar benchmarking approach
+- Add more language runtimes
+- Implement more sophisticated memory profiling
+- Create visualization tools for result comparison
+
+## Conclusion
+
+This benchmark provides insights into the concurrent task handling capabilities of different language runtimes, highlighting the evolving landscape of asynchronous programming in 2025.
