Attachment I/O limit Setting in PHP.INI

Post by Edward572 » Fri Dec 16, 2016 7:05 pm

Hello Everyone,
phpbb forum version: 3.1.10

Host: godaddy.ca
Max i/o to host disk is 1,024KB/Sec, so if your downloading an attachment from phpbb forum Site hosted at my host your entire site(s) are limited by this disk i/o limitation.
Not quite sure if this is a phpbb question or a PHP.ini or extension request, please move to proper area if in wrong spot.

Large files uploaded past 64MB seem to fail, even with PHP.ini set to higher in root folder. I go in to my godaddy.ca c/p and watch the i/o max out when uploading or downloading, and then I think the site throttles down and connection is broken, and when downloading you can continue, but if the file is large, you may need to repeat a few times and get it all.

Not sure if it has a time limit for script in phpbb or PHP.ini or server setting maxes.

With that all in mind is there a way to limit upload or download speeds to stop the connection from maxing out hosts limits, say 512KB/Sec limit stoping the host from breaking the connection? Hopefully something simple...

Thanks in advance.

ADD1: Further reading, limit imposed on entire hosting account, so even if I get one site under the limits, if other sites need disk resources it still may max out and disconnect connection.

So PHP.ini script maybe that has a max say of 896KB/Second Max, leaving 128KB as a top end buffer. Then something that feels the KB usage of all sites and divides the 896KB disk i/o between all sites equally, I kind of QOS, as the connections finish the BW is increased on the Remaing connection, but since host max is never reached the connections stay until download / upload is complete on all sites.

Not sure if this can even be done, I'll keep reading and add if I find anything that helps.

Code: Select all

<?php
set_time_limit(0);
// change this value below
$cs_conn = mysql_connect('localhost', 'root', '');
mysql_select_db('shareit', $cs_conn);

// local file that should be send to the client
$local_file = $_GET['file'];
// filename that the user gets as default
$download_file = $_GET['file'];

// set the download rate limit (=> 20,5 kb/s)
$download_rate = 85; 
if(file_exists($local_file) && is_file($local_file)) {
    // send headers
    header('Cache-control: private');
    header('Content-Type: application/octet-stream'); 
    header('Content-Length: '.filesize($local_file));
    header('Content-Disposition: filename='.$download_file);

    // flush content
    flush();    
    // open file stream
    $file = fopen($local_file, "r");    
    while(!feof($file)) {

        // send the current file part to the browser
        print fread($file, round($download_rate * 1024));    

        // flush the content to the browser
        flush();

        // sleep one second
        usleep(200);    
    }    

    // close file stream
    fclose($file);}
else {
    die('Error: The file '.$local_file.' does not exist!');
}




if ($dl) {
} else {
    header('HTTP/1.0 503 Service Unavailable');
    die('Abort, you reached your download limit for this file.');
}
?>
Cheers All, Have A Good One
