Assume #16916 as baseline. The E2E takes 1395.082s.

It introduced TestAuthority which takes 18.39s. And after #16997, it takes 50.05s.

It introduced TestInPlaceRecovery which takes 17.37s.

Ideally, it should increase 140.07s. It's not larger than 1800s timeout value.

However, we run E2E cases 3 times. By default, we run E2E cases with -cpu 1,2,4. That means that we run 3 times.

1395.082s + 140.07s * 3 = 1815.292s > 1800s

$ go help testflag

 -count n
            Run each test, benchmark, and fuzz seed n times (default 1).

            If -cpu is set, run n times for each GOMAXPROCS value.
            Examples are always run once. -count does not apply to
            fuzz tests matched by -fuzz.

I don't think we should run E2E with different GOMAXPROCS value. All the TestXYZ are used to control etcd process and we don't set GOMAXPROCS env to etcd process. So, we don't need -cpu setting for E2E.

Closes: #17241

Thanks for the analysis.

I suggest one of the following solutions,

  • change the default value for TEST_CPUS to "1,4".

    etcd/test

    Line 120 in d441d74

    TEST_CPUS="1,2,4"
  • or breakdown linux-amd64-e2e into two targets: linux-amd64-e2e-1-cpu and linux-amd64-e2e-4-cpu.
  • [preferred] or just add an option CPU=4 for the target linux-amd64-e2e in tests.yaml (consistent with the main`` and release-3.5 branches)

Assume etcd-io#16916 as baseline. The E2E takes `1395.082s`.

* etcd-io#16988

It introduced `TestAuthority` which takes `18.39s`.
And after etcd-io#16997, it takes `50.05s`.

* etcd-io#16995

It introduced `TestInPlaceRecovery` which takes `17.37s`.

* etcd-io#17144

  - New `TestHTTPHealthHandler` takes `29.9s`
  - New `TestHTTPLivezReadyzHandler` takes `35.20s`

* etcd-io#17173

  - New `TestMemberReplace` takes `7.55s`.

Ideally, it should increase `140.07s`. It's not larger than `1800s`
timeout value.

However, we run E2E cases 3 times. By default, we run E2E cases with
`-cpu 1,2,4`. That means that we run 3 times.

`1395.082s` + `140.07s * 3` = `1815.292s` > `1800s`

```bash
$ go help testflag

 -count n
            Run each test, benchmark, and fuzz seed n times (default 1).

            If -cpu is set, run n times for each GOMAXPROCS value.
            Examples are always run once. -count does not apply to
            fuzz tests matched by -fuzz.
```

I don't think we should run E2E with different GOMAXPROCS value. All the
`TestXYZ` are used to control etcd process and we don't set GOMAXPROCS
env to etcd process.

Set `CPU=4` to align with main and release/3.5.
