GitHub CI Jobs Slower than Usual?

I’ve noticed this with all of my recent PRs.

But here’s one from a few days ago, for NoMacs:

Looking at the raw logs, with timestamps, illustrates the issue.

The first dependency started installing at 3:33pm:
2021-04-24T15:33:40.0051560Z Installing dependency (1 of 265) 'bzip2' with variants '' (requesting '') ... [OK]

While the last dependency finished installing at 5:27pm, two hours later:
2021-04-24T17:22:49.4607320Z Installing dependency (265 of 265) 'qt5-qttools' with variants '' (requesting '') ... [OK]
2021-04-24T17:27:26.6862050Z ##[endgroup]

The last one is a great example: While QT5 isn’t a small port, it required a 5-minute installation time? Though it isn’t limited to that specific port, as the entire dependency installation process is slow.

Is this normal/expected?

Non-distributable packages are downloaded from a private server that only the CI systems have access to. If the CI system is not able to reach our private server for some reason, CI would need to build non-distributable packages from source, which could certainly take hours longer than downloading the binaries depending on what the dependencies are.
