Can you you find the transaction-id of the GET request for the download in the

 Hi experts


I finished the swift installation following the install 
guide(http://docs.openstack.org/project-install-guide/object-storage/draft/get_started.html),
 file&#xA0;upload&#xA0;&#xA0;is very fast, but file download is extremely slow, 
why ?
