Add an index to the `store` column on `uploads`. This makes counting local uploads faster. Also, there is no longer need to check for objects with `store = NULL`. See https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/18557 --- ### Query plans Query: ```sql SELECT COUNT(*) FROM "uploads" WHERE ("uploads"."store" = ?

Just select your operating system, download the respective package (Debian or RPM) and install it using the system's package manager.
There are various other options to install GitLab, please refer to the installation page on the GitLab website for more information.
You can access a new installation with the login root and password 5iveL!fe, after login you are required to set a unique password.

Install a development environment
To work on GitLab itself, we recommend setting up your development environment with the GitLab Development Kit. If you do not use the GitLab Development Kit you need to install and setup all the dependencies yourself, this is a lot of work and error prone. One small thing you also have to do when installing it yourself is to copy the example development unicorn configuration file:
cp config/unicorn.rb.example.development config/unicorn.rb
Instructions on how to start GitLab and how to run the tests can be found in the getting started section of the GitLab Development Kit.
