## Performance considerations

If you're using Visual C++ component extensions C++/CX to create your Universal Windows Platform (UWP) app, we recommend that you use plain-old-data (POD) types together with contiguous storage—for example, `std::vector` or C-style arrays—for data that will be used with C++ AMP. This can help you achieve higher performance than by using non-POD types or Windows RT containers because no marshaling has to occur.

This can help you achieve higher performance than by using non-POD types or Windows Runtime containers because no marshaling has to occur.

In a C++ AMP kernel, to access data that’s stored in this way, just wrap the `std::vector` or array storage in a `concurrency::array_view` and then use the array view in a `concurrency::parallel_for_each` loop:
