In answer to the question  "how much ram should MDK be using?" -

The answer is ALL OF IT!

This one comes up on a frequent basis because people are used to the way 
Windows does it.

Windows will load up every DLL it finds in the system folder when it boots, 
and then loads apps into the remaining RAM. Any unused RAM is idle (wasted)  
If it starts to fill up the available RAM the system starts acting weird 
(BSOD), and so people are naturally alarmed if the RAM fills up.

Linux by contrast loads nothing into RAM until it is needed. The Swap space 
acts as an extension to RAM so any idle process ends up in swap space where 
it is consuming no resources. Any RAM which is not being used for active 
applications/libraries is dynamically allocated as hard drive cache. This 
means that every time there is a disc read, there is a high probability that 
the data is actually resident in memory and the access time is reduced. If an 
application needs more RAM some of the drive cache will be written back to 
disc and memory is dynamically allocated.

This is how a *real* operating sytem handles memory. :-)

So do not worry. Having your memory 100% used is perfectly normal. The only 
time to worry is when an application suffers a 'memory leak' and starts using 
more and more memory. You will notice this when the swap space becomes more 
and more active, and the system will become sluggish. You can see in the 
monitoring apps (like KDE System Guard) how much memory is allocated to each 
app.
