This is a holiday-crunch emergency.

I'm dealing with a client from whom we need to download many large PDF docs 
24x7, several thousand per hour, all between a few hundred K and about 50 MB. 
Their security process requires the files to be downloaded via https using a 
big long URL with lots of credential parameters.

Here's how I'm doing it. This is on Windows, a quad Xeon with 16GB RAM:

$ctx = stream_context_create(array('http' => array('timeout' => 1200)));
$contents = file_get_contents($full_url, 0, $ctx);
$fp = fopen('D:\\DocShare\\'.$filename, "w");
$bytes_written = fwrite($fp, $contents);

It's WAY TOO SLOW. I can paste the URL into a browser and download even the 
largest files quite quickly, but the PHP method bottlenecks and cannot keep up.

Is there a SUBSTANTIALLY faster way to download and save these files? Keep in 
mind the client's requirements cannot be changed. Thanks for any suggestions.

try readfile()

Kind regards
