I'm attempting to upload a 5MB PDF file to DMX.  I can FTP the file in 2 minutes 23 seconds.

When I use the TelerikUpload, it moves only 270 bytes per second and eventually times out.  When I use the CAUpload, it shows 0% progress and then says "Upload Error: Too Many Files."  I have better luck with the AspnetUpload.  It takes just under 3 minutes.

Any ideas?  How should I start to debug this?

The site is hosted with PowerDNN, an excellent host here in the US, so I don't suspect an infrastructure problem.

Hi Carter,

Upload speed is primarily determined by your own up link from where your client PC/browser is. As you mention the server down speed (i.e. data moving into the server) is probably not an issue. Most people are on ADSL connections which means they have a limited up speed.

The code that is running while uploading is negligable. So the chance that this is a performance issue of the web application is very small. All the app needs to do is receive bytes and write them to disk.

Regards,
Peter

O, yes, to debug:

1. Go to another PC/Network. An internet cafe/library/etc. Check if there are any differences.
2. If you can RDP into the server try the site on the server if this is possible. Then you can cut out the network all together.

3. Switch upload provider. Select aspnet Upload provider on the Main Options page.
 

- edit - I just noticed you tried FTP and that is faster. So maybe this is not it. Still I advise to try the above.
