That might be a bottleneck. If you could modify your function so that
it can process arrays, you should get better results. Of course, that
depends on the actual function...
When I asked whether you really needed datetime objects, I was
thinking about the actual datetime.datetime objects, not about objects
having, say, a `day` or `hour` property. If you send an example of
function closer to your actual need, I may be able to help you more.
