Description Marko Myllynen 2017-02-06 11:34:07 UTC
Description of problem:
When pushing an image of ~500 MB I see with Docker v1 Registry something like:

 4646 root	20   0 3820600  79076  14608 S 141.7  0.1  21:07.32 dockerd-current
12979 root	20   0  287152  37744   3828 S  17.5  0.1   0:07.93 gunicorn

However, with Docker v2 Registry I see:

 4646 root	20   0 3821912  82784  14644 S 408.6  0.1  21:48.41 dockerd-current
13919 root	20   0 1397492  24076   6368 S  50.3  0.0   0:06.47 registry

This looks unexpectedly high CPU usage, would it be possible to optimize this?

Thanks.
