By default, we write to the "authorized_keys" file to support Git
over SSH without additional configuration. GitLab can be optimized
to authenticate SSH keys via the database file. Only uncheck this
if you have configured your OpenSSH server to use the
AuthorizedKeysCommand. Click on the help icon for more details.

Confirm that SSH is working by removing your user's SSH key in the UI, adding a new one, and attempting to pull a repo.
> **Warning:** Do not disable writes until SSH is confirmed to be working perfectly because the file will quickly become out-of-date.
In the case of lookup failures (which are not uncommon), the `authorized_keys` file will still be scanned. So git SSH performance will still be slow for many users as long as a large file exists.
You can disable any more writes to the `authorized_keys` file by unchecking `Write to "authorized_keys" file` in the Application Settings of your GitLab installation.
![Write to authorized keys setting](img/write_to_authorized_keys_setting.png)
Again, confirm that SSH is working by removing your user's SSH key in the UI, adding a new one, and attempting to pull a repo.
Then you can backup and delete your `authorized_keys` file for best performance.
## How to go back to using the `authorized_keys` file
This is a brief overview. Please refer to the above instructions for more context.
