Finally resolved the issue. Bought some cat5e (or, as Belkin likes to
call it FastCAT5e) and now, one-way only transfer Windows->Linux is
around 10MB/s, Linux->Windows increases to close to 7.5MB/s, and
full-duplex is around 3-5MB/s each way, at the same time. Considering
it's a cheap switch, I'm satisfied :) Some interesting full-duplex
issues (seems to hickup and lock on one of the sides sometimes).

Final word: cable was the problem.

Thanks to all who helped!
