Don't forget the buffers/cache.
The 2.5G you're missing is what is used in the buffers/cache line.
At least, that is how I see it.
Also, I generally look at the percentages used for the memory to find the
memory-hogs.
And your tv-viewer (java) is using quite a bit as well.
Maybe someone with more experience with tv-viewer apps can take a look and
maybe give a few pointers?
