Adobe Reader installer download speed differences: FTP much slower than HTTP

Posted by jpluimers on 2014/08/17

The FTP download is much much slower than the http one:

4.2 MB/s – 73.4 MB of 73.4 MB: http://ardownload.adobe.com/pub/adobe/reader/win/11.x/11.0.08/en_US/AdbeRdr11008_en_US.exe

119 KB/s – 24.6 MB of 73.4 MB: ftp://ftp.adobe.com/pub/adobe/reader/win/11.x/11.0.08/en_US/AdbeRdr11008_en_US.exe

This over the same 50 megabit fiber connection.

So basically you have to:

  1. Browse the ftp://ftp.adobe.com/pub/adobe/reader/win/11.x  for a version in your language (en-US for intance has the youngest full install at ftp://ftp.adobe.com/pub/adobe/reader/win/11.x/11.0.10/en_US/ as younger versions only contain update MSP files, for instance in ftp://ftp.adobe.com/pub/adobe/reader/win/11.x/11.0.16/misc/)
  2. Copy the download URL
  3. Replace the ftp://ftp.adobe.com/pub/adobe/reader/win with http://ardownload.adobe.com/pub/adobe/reader/win (you cannot browse the latter as it genrates “Not Found; The requested URL /pub/adobe/reader/win/ was not found on this server.”)
  4. Download the URL that you just assembled

    Is FTP dying? :) I’ve noticed Adobe FTP is slow while downloading reader’s security patches too.
