Please know we are doing everything possible to mitigate the download response times and are actively seeking solutions. In the interim, may I suggest using a "download manager" which would help the process along. Given that the file is several gigabytes, download managers allow users to 'resume' downloads if there is any interruption in the process, making it possible to get the complete file intact. Some browsers have plugins and add-ons for free to help in this area.
If this is not a viable option to do, due to IT policies at your organization, I completely understand. Please enter in a support request from the My Support Portal (MSP) to request an alternative solution if downloading from this site is not possible.
