What is a realistic Kbps transfer rate?

You're typically going to be limited by the writing speed of your destination computer. However, this stuff can get complicated very quickly, and even involve the computational speed on the computer(s) doing the work. It doesn't have to make sense; it just does. Getting it to make sense, and not be bottlenecked on the friggin' CPU can be a challenge. I think in this case that I saw on my computers, some low-level system resource got filled or stressed, and that showed up as a CPU bottleneck because the system was doing far too much mucking around with that system resouce...
Whether or not you have write caching enabled can make a difference. The direction in which you're doing the transfers can make a difference. So far, it's better to copy the file from the destination computer, but who knows what all the facets of the universal rule would be.
File transfer speeds are typically discussed in MB/s (either as per 10^6 bytes per second, but also as per 2^20 bytes per second). It's sad, I know, but these days I'm happy if I can sustain a 30 MB/s (comparable to 300 mbps) transfer over a (very) large set of files, using RAID.
Perhaps I'll figure out that system bottleneck in time, but for now I see large transfers / backups degrading to 10 MB/s and even lower before very long, and there we're looking at standard LAN speeds, no longer gigabit speed.
