pull hangs even if all the files needed exist in cache

I've noticed that dvc pull hangs for a few seconds every time you run it. Even if all the files needed exist in cache.

(.env) [ivan@ivan ~/Projects/example-get-started]$ dvc pull
Preparing to download data from 'https://remote.dvc.org/get-started'
Preparing to collect status from https://remote.dvc.org/get-started
[#########                     ] 30% Collecting information

Is it expected or just is it just a lack of optimization?

Can be reproduced with the example-get-started project and HTTP remote.

Lack of optimization. Here https://github.com/iterative/dvc/blob/0.34.2/dvc/remote/local.py#L684 we collect full-blown status even for an already present cache on dvc pull, which is causing that delay. Need to fix that by skipping collecting status for already present cache files on pull/fetch. Thanks for reporting this! 🙂
