We installed a Sharepoint 2013 server with a separate Database in a OOTB default configuration.
The issue we have is that the first user (in a period of time) who tries to open a file has to wait minutes. All other users after that have no problems at all with opening the other files. Files open instantly.
Blob cache is enabled and we implemented a Powershell wake-up script (running every 10 min) to keep the front-end 'awake'. Our document library is still under 1K files. What can cause this issue?
