So your windows installation of R-3.4.0 can solve this in 600ms? Or is 
yoiur another OS?

For winbuilder, it could be it was heavily loaded, but even then it 
should never take more than twice as long as on an idling machine. Then 
winbuilder has server CPUs with lots of cores hence operates at a lower 
frequency, altogether not more than 3-4 times the the time you got can 
be expected.

Best,
