If you think that you are beter at memory management than your computer, 
you can try the following commands:

sudo swapoff -a
sudo swapon -a

This forces the kernel to clear all swap memory.
Just like RAM defrag, it is utterly pointless, but at least you have the 
idea that your computer is obeying your commands.



I have looked at the feature set of System Mechanic, and I can give you 
the following Linux alternatives:

Improve startup: the Linux devs are doing this for you, with every new 
release. The new event-driven bootup system, Upstart, is a big 
improvement. So you don't need that.

Optimize registry: Linux doesn't have a registry, so not needed

Delete junk files: Bleachbit

Tune automagically: not needed, the Linux kernel does that for you

Protect your system: at the time of writing, there are no known Linux 
viruses in the wild. Ubuntu Linux comes with a firewall.


Is there anything else that you need? Please describe in detail what you 
are missing and we will explain what the alternatives are, or why you 
don't need it.

You should also know that Linux follows the principle of "do only one 
thing, and do that good". System Mechanic is a very complex program that 
does a lot of different things that are totally unrelated. It's one 
program that tries to do 10 things. On Linux you would have 10 different 
programs that do only one thing.
