Adobe Acrobat Pro 11.0.18 - When you login, the first PDF takes 15-20 seconds to open.

[bethf29718075]

We work in a virtual environment and are testing to see if we can at least cut down the time to open up a PDF. The scenario is below:

When logging in, click on the PDF file. It takes 15-20 seconds to open. Close the file and reopen that file or any other one, it opens instantly.

Things we have troubleshooted so far are:

1. Disabling Enhanced security via preferences.

2. Disabling messages prompts upon Acrobat launch.

3. Removing the app-data folder to Adobe

Please advise if there is something else we can do to shorten the time span for opening a PDF file. Thanks in advance!
