Testing rsync transfer rates, using the rsync command: 'rsync -azP --stats', measuring actual disk space consumed on the destination filesystem per minute:
1. pull from hgwdev to hgdownload: 39 Mb/sec = 2360 Mb/min = 141,600 Mb/hour = 3,398,400 Mb/day (single rsync) 2. pull from hgdownload to cloud: 18 Mb/sec = 1080 Mb/min = 64,800 Mb/hour = 1,555,200 Mb/day (single rsync) 3. pull from hgdownload to cloud: 37 Mb/sec = 2230 Mb/min = 133,800 Mb/hour = 3,211,200 Mb/day (two rsync) 4. pull from hgwdev to cloud: 768 Kb/sec = 45 Mb/min = 2,700 Mb/hour = 64,800 Mb/day (via ssh, not rsh) 5. internal cloud to cloud copy: 35 Mb/sec = 2150 Mb/min = 129,000 Mb/hour = 3,096,000 Mb/day (volume to volume) 6. second example cloud to cloud: 12 Mb/sec = 770 Mb/min = 46,200 Mb/hour = 1,108,800 Mb/day (volume to volume)
