First, it has become extremely slow. It takes a very long time to click around and do things in the Web UI. It takes a very long time to even type let alone run commands in an SSH shell. The Windows file shares are also just as slow.
Second, as time ticks on since boot, the buffer fills up more and more and the data it's uploading gets further and further behind. After 12 hours of uptime, the data upload is 10 minutes behind and there's lots of stuff in the buffer.
These problems persist after soft reboots and power cycles.
