The gopls regtests are slow, particularly on openbsd and darwin due to (we believe) kernel locking behavior. For this reason we've excluded them when testing with -short on several builders where they regularly time out.

But they usually run relatively quickly on Linux, so it's surprising (to me at least) that they are timing out on the new linux-arm builder. This is probably worth investigating at some point.

Do you know about the regtest performance on the linux-arm-aws builder?

The linux-arm builder is not new, has a known issue and is known to be slow (we disabled trybots because of many problems). The linux-arm-aws builder is newer (#41867) and has more resources allocated, so you may get a better signal about gopls behavior on linux/arm from it.

Ah I see, I probably only noticed the linux-arm failure due to recent awareness of other failures (particularly openbsd).

I can try out the linux-arm-aws builder in 2021.
