Any ideas from the gurus here?

Try finding this:

PHP Code:


		
			
echo $attachmentinfo[filedata];

and changing to:

PHP Code:


		
			
// UploadBandwithLimitHack 
 // Original line: echo $attachmentinfo['filedata']; 
 $bandwidth = 30; // Desired max. bandwidth in KB/s. 
 $i = 0; 
 while ($i < strlen($attachmentinfo['filedata'])) { 
   echo substr($attachmentinfo['filedata'], $i, 1024); 
   $i += 1024; 
   flush(); 
   usleep(1000000/$bandwidth); 
 } 
 // UploadBandwidthLimitHack

This is essentially what was posted above, but for the filedata with vb2 itself :)

I did that. All it did was make the download take longer to start, but once it started ti downloaded at the top speed it could and not the 30k i had set.

whats the point? this would force users to WAIT longer to download an image or a file, why not let them get it asap ..?

That is exaclty what i experience when downloading. I no want them to wait longer I just want to slow the speed at which they get it at.

Most users have a 100k/s line or higher... I want them to only be able to download my attachements at like 40k or so. Simply because we have files of 5+ megs..

when we have 100 users downloading those files at 100+k/s you can imagine what hapepsn to our line.

Problem is we are getting bursts as high as 1400kbps and the datacenter is wanting more money.

Specially when these bursts are at times consecutive for like 30 minutes.

Also because of the high bursts at time the site it self becomes rather slow. While server loads at a minimum. What is happenign is some users are using up all the of the line downloading and leaving nothing or barely nothing for users who are just surfing. causing the site to drag.

If i could cap the downloads then it would be equal to all.

I have manage to get server side files to download at 40k/s if bigger then 1 meg, however that does not effect mysql attachements.

Any help would really be appricated.

It won't change download speed... but unlike the orginal, it will only give the download in sections at a time.

The original would only do this with the header which is why it took longer to start.

At least check the code to see it's different :rolleyes:
