Comment 4 for bug 1654645

Unfortunately this patch doesn't fix the issue (though it should help after the issue itself got fixed).

The slow part is happening a few lines before: https://github.com/openstack/python-openstackclient/blob/master/openstackclient/api/object_store_v1.py#L372-L377

I just run a download of a 10MB object using the merged patch from openstackclient, and it took 204 seconds (compared to around 2 seconds with the swift CLI).

I continue investigating this.
