Async Clipboard API take more time compared to DataTransfer API to read/write data in System Clipboard #190

We observed that the async clipboard api (navigator.clipboard.read or navigator.clipboard.write) take more time to read/write data in system clipboard.

I have created the below sample app in glitch.

As you can see with DataTransfer API it takes ~1 ms to copy and ~30 ms to paste. But it takes ~650 ms to copy and ~300 ms to paste when we use Async Clipboard API.

Looks like this is a chromium issue so I opened a bug for investigation: https://bugs.chromium.org/p/chromium/issues/detail?id=1475750. Closing this issue as this has nothing to do with the clipboard web API spec.
