I have been testing for 24 hours and I have been a bit naughty because my first test is quite the test…
In my opinion, it doesn’t seem to handle large amounts of files very well. For my first test I am trying to sync 940k files (around 137GB) between too machines over the internet (both have a 1GB pipe) and after 24 hours only 60k and 4GB have been transferred. It doesn’t seem to be a problem with thespeed between the nodes, some transfer happens at 20 or 30 Mbps then it all stops and both machines start using the CPU heavily until there is another burst of data.
Hope it helps, suggestions are welcomed.
