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 upload  is very fast, but file download is extremely slow, why ?


[root at controller admin]# time openstack object create container1 cirros-0.3.4-x86_64-disk.img
+------------------------------+------------+----------------------------------+
| object                       | container  | etag                             |
+------------------------------+------------+----------------------------------+
| cirros-0.3.4-x86_64-disk.img | container1 | ee1eca47dc88f4879d8a229cc70a07c6 |
+------------------------------+------------+----------------------------------+

real    0m3.807s
user    0m2.127s
sys     0m0.161s





[root at controller /]# time  openstack object save container1 cirros-0.3.4-x86_64-disk.img
real    5m51.489s
