I have found win-builder timings come close,  but only close.  My experience is 
that the CRAN timings were uniformly slower than those on win-builder.  But I 
also find that I can get quite significant differences between 
win-builder-release and win-builder-devel.  So I also take the slowest that I 
can find as a basis,  and assume the actual times will be slower than that.

winbuilder and the WIndows check machione for the regulöar checks are actually identical.

  And one more (last for a while): presumably there is no way to check CRAN 
windows timing without submitting to CRAN ... ?  (I will obviously do my best by 
doing arithmetic on the tests that I set to be skipped, but it would be nice to be 
able to double-check without wasting everyone's time ... I guess if I knew that 
CRAN submissions would *always automatically* be rejected with Windows test 
times>10 min, I could use CRAN submission itself as my test ... but maybe 
that's a bad idea?)

Thanks Dirk. Yes, for lme4 the tests for each archiecture take longer than 5 
min, so the overall check time exceeds 10 min.
So one can follow Dirk's advise.
As a general remark for others who will read this in the future:
tests should test the software, but it is generally not important to have real 
world examples. Small data and few iterations are typically sufficient for 
tests.
It is also possible to run less important tests only conditionally if some 
environment variable is set that you only define on your machine.
Best,
Uwe Ligges

Yes.

(kind of a pain as there's no low-hanging fruit - other than the 'testthat' 
tests, none of the individual test files take longer than 15sec, although this 
is doubled because they have to be run on 386 and x64 ...)

It's under your control. You can detect 'are we on Windows' and branch or, as
I do with test runner I use, exit_file("...") based on such conditions.

there are strong rev dependencies so the package needs to be further checked? 
(That seems unlikely as it explicitly asks me to resubmit)

No. If there were any (even false positive ones) they'd be listed there.

Hth, Dirk
