Code explanation

Solution

Here’s a simple Go program that performs concurrent HTTP requests and measures response times. The ab.go code tests the performance of a web service by sending multiple concurrent HTTP requests to a specified URL and measuring response times. It provides basic performance metrics such as:

Total time taken
Requests per second
Fastest time
Slowest time
Average time

These metrics can give us a basic understanding of how the web service is performing under the specified concurrency and request load.
