I think there have been two similar threads recently, and I want to be sure I'm not confusing them. So:
- How large is the db? By which I mean how much disk space does the data directory occupy?
- What's the bandwidth of the network connection to the distant slave?
- What's the CPU & disk on each end?

Well, there's one error. Your command is rsync'ing each file individually, so of course each file is sync'd. Sync the
directoriesinstead--in other words leave off the * (but not the /) and let rsync decide which files need sync'ing.
