large file download and unzip

Just documenting the time taken etc. - downloading the 98 GB zip file from ESO's website,

  • On my machine with a single download segment, 3 Mbps, 3 days estimated, with our 10 Mbps network. 
  • On R's machine at college with their 1 Gbps network, Sat-night, Sun-morning, 4 segment download at around 15 Mbps. 1.5 MB per second. 15 hours. 10 segment download might have been faster. 
  • Copying from their NAS over their 1 Gbps internal network to the external hard disk - half an hour. 
  • Unzipping on my machine - around 4 hours with 7-zip.
