Glance + ceph is really slow

I have an Openstack newton cluster and I used ceph as a storage backend for glance images. But uploading images is very very slow.. Iam getting a warning always as below in glance-api.log

WARNING glance_store._drivers.rbd [req-b4b2b950-6fac-4581-9682-09290836d624 2cfe6360fd8d494c80ee2740b901e1e1 20d65370e91d428d8d83abb84b5c2c21 - default default] since image size is zero we will be doing resize-before-write for each chunk which will be considerably slower than normal

Why this is happening?? Any help to solve this issue is really appreciated..
