Surge is a command-line utility designed for HTTP load testing and benchmarking.
It's used to simulate multiple concurrent users accessing a website or API endpoint to evaluate its performance under stress. Surge takes a URL or a list of URLs as input and sends a specified number of requests concurrently.
It then collects statistics such as request latency, throughput, and error rates. This data is used to identify performance bottlenecks and determine the system's capacity. Surge is relatively lightweight and easy to use, making it a valuable tool for developers and system administrators who need to quickly assess the performance of their web applications. Its features include: generating reports about HTTP response codes, time spend on the request and data transfer.

Surge may not accurately simulate real-world user behavior due to its simple request patterns. It's best used for quickly identifying performance bottlenecks rather than simulating complex user interactions.

Example 1: Load test a single URL with 1000 requests and 50 concurrent users:
surge -n 1000 -c 50 http://example.com

Example 2: Read URLs from a file and load test with a timeout of 10 seconds:
surge -f urls.txt -t 10
