Connection with Net/SSH2.php to Huawei Olt MA5680T is very slow

I implemented a php script to communicate with my Huawei Olt MA5680T through the phpseclib SSH2.php library but the execution time of any remote operation on the Olt is extremely slow, about 40 seconds. I tried sending simpler commands but the result doesn't change.

I'm currently using this function to connect via ssh to the device:

function sessione_ssh($olt_id) {
global $ssh;
global $ip_olt;

$ssh = new Net_SSH2($row_olt['olt_ip']);
if (!$ssh->login($row_olt['olt_user'], $row_olt['olt_pass'])) {
exit('Login Failed');}
$ssh->setWindowColumns(200);
$ssh->read('MA5680T>');
$ssh->write("enable\n");
$ssh->read('MA5680T#');
$ssh->write("mmi-mode enable\n");
$ssh->read('MA5680T#');
}

With the same library I connect to other devices and execute scripts that are executed quickly, the problem occurs only with this device. I tried reading the logs but I don't detect any errors in the communication between the ssh2.php library and the olt MA5680T.

What could be the problem? this is the logs: https://pastebin.com/n9wHdLaj

Thank you so much for the support I receive from you for my project

UPDATE

The suggestion received from @neubert seems like the right way to decrease the script execution time. With the function I posted above I now actually have an execution time of about 3 seconds (absolutely acceptable). so using the same logic I inserted the correct prompt into all read() calls but it doesn't always work! when I enter a submenu of the prompt example: $ssh->write("interface gpon " . $frame . "/" . $board . "\n"); then I set the read call like this: $ssh->read('MA5680T(config-if-gpon-' . $frame_ont . '/' . $board_ont . ')#'); but I always get long times with 10 second timeouts like before. This is the link to the prompt from the terminal https://pasteboard.co/ldCa4JlnsfnL.jpg What could be the problem? this is the log:

Solution

I solved it thanks to @nubert by setting the correct prompt for each $ssh->read(); Example: $ssh->read('MA5680T>');,$ssh->read('MA5680T(config)#');
