It is a minor problem but I actually don't understand how proced is
calculating the percentage. If I compare the percentage memory value
from proced with that of top I see that top show a value 4 times that of
proced. Before noticing this I though it was due to proced including
swap but the amount swap is half the amount of ram so I would have
expected the factor to be 1.5. Other programs also show values very
similar to top. The problem is that if I don't remember this fact, I
don't catch the high memory usage.

Comparing with top, I notice that value is top changes much more quickly
compared to proced and better reflects the current load. The amount of
total cpu time used by a process is identical between top and proced so
I had assumed that they differed by how the calculated the current load.
