Implemented BenchmarkSample function in the most efficient way possible to my current knowledge.

After understanding the code and problem, I identified operations to improve performance and efficiency to some extent. By leveraging my programming skills, I realized that some precomputation may be useful.I have taken reference of BenchmarkRawUDP function and have made following changes :

• Precomputing connections instead of building connection for each writer function call (i.e. b.N times).

• Instead of sending UDP packets sequencially now we are sending concurrently utilizing goroutines.

• Number of iterations per second - Almost 2 times better.
• Time for processing each iteration - Almost 1.85 times better.
• Bytes allocated per iteration - Bit better.
• Number of allocations per iteration - Bit better.

• We are not caring about the order in which each reader receiving messages.
• Increased resource usage, as each thread requires its own set of resources such as memory and CPU time.
• Precomputing the connection pool improves performance by reducing latency since connections are established beforehand. However, Preallocation of resources may not be suitable for scenarios where the number of connections ( readersCount ) varies dynamically.
