tellesnobregatosky, looking at sftp, there are some interesting things using the put() method. For example, using sshclient.open_sftp() the transfer for a 300MB takes ≃3:20 minutes while SFTPCLient directly takes ≃2:3019:39
tellesnobregasahara uses ssh.open_sftp()19:40
tellesnobregafor 100MB file it took around 1:05 minutes using sftp_client, seems like put has a linear growth19:46

openstackgerritTelles Mota Vidal Nóbrega proposed openstack/sahara master: Switch sahara swift to work with keystone v3  https://review.openstack.org/53591519:58
toskytellesnobrega: so maybe there is some way to solve the problem with paramiko20:35
tellesnobregatosky, probably, we would have to use put instead of file.write(), for that we need to write the file we get from swift into the sahara machine so we can send it to the remote machine20:36
toskyuhm uhm, but then isn't there a double transfer?20:37
tellesnobregathe way we do write now is, get raw data from swift and write it into remote machine20:37
tellesnobregathe double transfer is already there in a manner20:38
toskyonly memory, not disk20:41
tellesnobregatrue20:41
tellesnobregamaybe it is time to take look into other ssh libraries20:41
toskyI don't think that there are many20:42
tellesnobregaprobably not as complete, maybe we can do something specific for file transfer20:45
tellesnobregadon't really know where to go from now20:56
tellesnobregago to now20:56
tellesnobregamaybe we can improve with pipeline, changing buffer20:57
toskydid you check the two properties that I mentioned yesterday?21:02
toskywindow_size and max_packet_size21:02
