Are there any best practices for handling fast-paced script execution in PHP when connecting to remote servers via SSH?

When handling fast-paced script execution in PHP when connecting to remote servers via SSH, it is important to properly manage the SSH connection resources to avoid timeouts and performance issues. One best practice is to use connection pooling to reuse established SSH connections instead of creating new ones for each request. 

// Initialize SSH connection pool
$sshConnections = [];

function getSSHConnection($server) {
    global $sshConnections;

    if (!isset($sshConnections[$server])) {
        $ssh = new Net_SSH2($server);
        $ssh->login('username', 'password');
        $sshConnections[$server] = $ssh;
    }

    return $sshConnections[$server];
}

// Example of using the SSH connection pool
$server = 'example.com';
$ssh = getSSHConnection($server);

// Execute commands on the remote server
echo $ssh->exec('ls -la');
