We recommend having at least [2GB of swap on your server](https://askubuntu.com/a/505344/310789), even if you currently have
enough available RAM. Having swap will help reduce the chance of errors occurring
if your available memory changes. We also recommend [configuring the kernel's swappiness setting](https://askubuntu.com/a/103916)
to a low value like `10` to make the most of your RAM while still having the swap
available when needed.
Notice: The 25 workers of Sidekiq will show up as separate processes in your process overview (such as top or htop) but they share the same RAM allocation since Sidekiq is a multithreaded application. Please see the section below about Unicorn workers for information about how many you need of those.

For all machines that have 2GB and up we recommend a minimum of three unicorn workers.
If you have a 1GB machine we recommend to configure only two Unicorn workers to prevent excessive swapping.
To change the Unicorn workers when you have the Omnibus package please see [the Unicorn settings in the Omnibus GitLab documentation](https://gitlab.com/gitlab-org/omnibus-gitlab/blob/master/doc/settings/unicorn.md#unicorn-settings).
