In what ways can the code provided in the forum thread be optimized or improved for better performance when running on a Linux server?

The code provided in the forum thread can be optimized for better performance on a Linux server by reducing the number of file system operations. One way to achieve this is by caching the results of file system operations in memory to avoid repeated reads and writes. Additionally, using efficient data structures and algorithms can help improve the overall performance of the code. 

<?php

// Example code snippet with optimized file system operations using caching

// Initialize an empty array to cache file system operations
$cache = [];

function getFileContents($filename) {
    global $cache;
    
    if (isset($cache[$filename])) {
        return $cache[$filename];
    } else {
        $contents = file_get_contents($filename);
        $cache[$filename] = $contents;
        return $contents;
    }
}

// Example usage
$filename = 'example.txt';
$fileContents = getFileContents($filename);
echo $fileContents;

?>
