Originally created by @juanfont on GitHub (Apr 30, 2022).

Currently we are facing a scalability issue in the number of clients that Headscale can handle. This becomes problem becomes very apparent while executing the integration tests.

As of April 30th we are targeting the following Tailscale versions:

(from integration_common_test.go)

	tailscaleVersions = []string{
		"head",
		"unstable",
		"1.24.0",
		"1.22.2",
		"1.20.4",
		"1.18.2",
		"1.16.2",
		"1.14.3",
		"1.12.3",
	}

and we are running 20 containers (in integration_test.go):

	s.namespaces = map[string]TestNamespace{
		"thisspace": {
			count:      15,
			tailscales: make(map[string]dockertest.Resource),
		},
		"otherspace": {
			count:      5,
			tailscales: make(map[string]dockertest.Resource),
		},
	}

I have temporarily reduced the number of containers in the integration tests at https://github.com/juanfont/headscale/pull/568, so we can have a more less functional pipeline.

Let's keep this issue to track the problem.
