Out of interest, how long does the full test suite take to run on windows? (Also, needs a rebase.)

[alexcrichton]

I, too, am curious about how this would affect cycle time. We definitely don't want cycle time to go up, so I think we should see how long the suite is on windows before merging.

[brson]

I can run a test.

[brson]

On win1 before removal check-fast took 16m; after, check-lite takes 24m.

[alexcrichton]

That doesn't sound nearly as bad as I thought it was, but it also may push the windows bots to being the slowest bots. I think that the linux bots would be faster by 10-20min at that point. That doesn't sound too bad, and we could always slim down slower portions of the windows test suite if necessary.

It sounds like we could largely speed-up Windows according to #8844 (comment).

[brson]

If check-lite is not fast enough we can change it to test fewer things.

[alexcrichton]

For the compile-fail test, is it possible to do // ignore-freebsd instead of // ignore-test? It would be a shame to lose them completely.

If so, r=me

Closing in favor of #13288
