How does perldoc and docs affect performance or memory usage?

Perl’s documentation tools, such as perldoc, allow developers to access comprehensive information about modules and functions. However, using these tools can affect performance and memory usage, especially in large codebases or when running scripts that require extensive documentation calls. When a script leads to multiple calls to perldoc or relies heavily on documentation at runtime, it may introduce overhead that affects execution time and memory allocation.

It’s essential for developers to consider these potential impacts, particularly in performance-critical applications. A balance should be struck between maintaining access to documentation and optimizing memory usage and performance during execution.

Here’s a simple example demonstrating how to use `perldoc` to check documentation for a Perl module:
