So the network bandwidth between the client and the server is as below . [ ID] Interval Transfer Bandwidth [ 3] 0.0- 1.0 sec 256 KBytes 2097 Kbits/sec [ 3] 1.0- 2.0 sec 512 KBytes 4194 Kbits/sec [ 3] 2.0- 3.0 sec 384 KBytes 3146 Kbits/sec [ 3] 3.0- 4.0 sec 640 KBytes 5243 Kbits/sec [ 3] 4.0- 5.0 sec 512 KBytes 4194 Kbits/sec [ 3] 5.0- 6.0 sec 640 KBytes 5243 Kbits/sec [ 3] 6.0- 7.0 sec 512 KBytes 4194 Kbits/sec [ 3] 7.0- 8.0 sec 512 KBytes 4194 Kbits/sec [ 3] 8.0- 9.0 sec 768 KBytes 6291 Kbits/sec [ 3] 9.0-10.0 sec 896 KBytes 7340 Kbits/sec [ 3] 0.0-10.3 sec 5760 KBytes 4597 Kbits/sec No, currently we don't use SLO with binary chunking . So same upload S3 takes around 20 min , so may be expected will be 20 - 25min for 2gb upload .

Hi List ,

We have an use-case where we upload large object (2GB - 4GB) via form post.
What we are observing is , it's taking 2 - 3hrs to get the upload completed .

Our Setup is consist of Haproxy => Swift-Proxy => Storage Node .
