# Performing operations in GitLab **(FREE SELF)**

Keep your GitLab instance up and running smoothly.

- [Rake tasks](../../raketasks/index.md): Tasks for common administration and operational processes such as
  [cleaning up unneeded items from GitLab instance](../../raketasks/cleanup.md), integrity checks,
  and more.
- [Moving repositories](moving_repositories.md): Moving all repositories managed
  by GitLab to another file system or another server.
- [Sidekiq MemoryKiller](sidekiq_memory_killer.md): Configure Sidekiq MemoryKiller
  to restart Sidekiq.
- [Multiple Sidekiq processes](extra_sidekiq_processes.md): Configure multiple Sidekiq processes to ensure certain queues always have dedicated workers, no matter the number of jobs that need to be processed. **(FREE SELF)**
- [Sidekiq routing rules](extra_sidekiq_routing.md): Configure the routing rules to route a job from a worker to a desirable queue. **(FREE SELF)**
- [Puma](puma.md): Understand Puma and puma-worker-killer.
- Speed up SSH operations by [Authorizing SSH users via a fast,
  indexed lookup to the GitLab database](fast_ssh_key_lookup.md), and/or
  by [doing away with user SSH keys stored on GitLab entirely in favor
  of SSH certificates](ssh_certificates.md).
- [File System Performance Benchmarking](filesystem_benchmarking.md): File system
  performance can have a big impact on GitLab performance, especially for actions
  that read or write Git repositories. This information will help benchmark
  file system performance against known good and bad real-world systems.
- [The Rails Console](rails_console.md): Provides a way to interact with your GitLab instance from the command line.
  Used for troubleshooting a problem or retrieving some data that can only be done through direct access to GitLab.
- [ChatOps Scripts](https://gitlab.com/gitlab-com/chatops): The GitLab.com Infrastructure team uses this repository to house
  common ChatOps scripts they use to troubleshoot and maintain the production instance of GitLab.com.
  These scripts are likely useful to administrators of GitLab instances of all sizes.

Add support for SSH certificate authentication Why and how to enable this is covered in the docs being changed here. This requires gitlab-org/gitlab-shell@2e8b670 ("Add support for SSH certificate authentication", 2018-06-14) which has been merged in and tagged as 8.0.0, so GITLAB_SHELL_VERSION needs to be bumped. Merging this closes gitlab-org/gitlab-ce#34572 see gitlab-org/gitlab-shell!207 for the gitlab-shell MR. Implementation notes: - The APIs being changed here are all internal, and their sole consumer is gitlab-shell. - Most of the changed code is a MR to gitlab-shell, see the gitlab-org/gitlab-shell!207 MR. That change covers why only some of the internal methods get a new "username" parameter, and why some others only get a "user_id". 2018-07-18 15:43:18 -04:00			`- Speed up SSH operations by [Authorizing SSH users via a fast,`
