Computer is always downloading

My MBP is always downloading something at the rate of 25-50KB/s. I see its numbers on Menu Meters and it looks like this:

User uploaded file

Then it periodically uploads at a similar rate. What can it possibly be downloading for days on end? Is there a Terminal based dump of network downloads? The computer is also doggishly slow with lots of spinning wheels. MacBook Pro 2011, 10.9.2.

What processes are getting the downloads? Perhaps Xcode documentation, iCloud/App Store synchronization, or background system updates are being used.


Mavericks seems to do a lot more caching - I regularly get pauses long enough for me to think mouse clicks didn't register or the system has crashed. I'm not sure what they are thinking or how much memory is assumed, but the system is definitely less responsive than earlier versions.

OS X does a number of things that might look like uploading and downloading: maintaining a connection with the router, testing iCloud for changes, looking for push notifications or software updates, even passing local information around using tcp ports. Computers (unlike humans) are always doing housecleaning when they're awake. That's probaby what you're seeing, unless you have some solid reason to think it's something else.
