My setup is as follows:
A strong desktop, with quad core CPU and a 7200RPM HDD. A weak three years old lenovo laptop, used as a media center, running Ubuntu.
They are connected using WiFi (N).
Often, while playing HD movies, the Ubuntu machine starts swapping background apps to make room for the active application that plays the movie. Movie playback performance is unaffected, there is no sensible thrashing, but if I switch to a different application afterwards I can feel the slowness of paging that memory back in.
Is it possible that using a swapfile on the hard drive of the desktop will give me better performance than the laptop's local hard drive?
