...Cause
Running Bitbucket Server as a user (either via Windows service or not) that is part of the Administrator group causes Windows to spend a lot of time running permission checks.
atlbitbucket
If you installed Bitbucket Server as a service using the installer as described on Getting started, you shouldn't be seeing this issue when it is run as a service. A user atlbitbucket is created and responsible for running Bitbucket Server. This user is not a member of the Administrator group. Please refer to Run the Bitbucket installer for more details on the atlbitbucket user.
Resolution
Resolution option 1 (recommended) - Reinstall Bitbucket Server as a local user
In order to change the Bitbucket Server user, the following procedure is the preferred option:
Stop the current Bitbucket Server instance
Install a new Bitbucket Server on the windows server by using the installer
Select a new installation directory
Select the existing home directory
Bitbucket Server is now up and running with the expected Windows user details
Resolution option 2 - Microsoft hotfix
If Bitbucket Server cannot be run as a non-administrator user, apply this hotfix http://support.microsoft.com/kb/2545833.
