I have had this laptop for about 3 months running Ubuntu and it is now considerably slow performing every function than when I first installed Ubuntu 12.04. I have tried running a virus scanner. I have turned on "preload". I am running "zram". Even tried "bleachbit" but nothing seems to help.

System performance, as I'm sure you are aware is a very complicated subject.
However, I think that it would be fair to say that at a basic level it's the result of three things;
- CPU Utilization
- Memory Utilization
- Disk Utilization
Use, the information below only as a guide to what May be slowing things down.
Ubuntu has a package called top for monitoring system processes and their CPU and Memory % utilization More information on the top command.
Using top you should be able to identify any processor, or memory hogging tasks.
- Open a terminal prompt,
- type
$ top, - Look at the top processes and their CPU and Memory utilization
Obviously, the list should not add up to 100% of CPU or Memory ;o).
If it does (or close >80%) you may look to increase the resources or reduce the load.
To reduce the load;
- Locate the processes that you do not need and make a note of its name,
- Exit
$ topusing(Ctrl-C), - Get the process details, type
$ sudo ps -ef | grep my-unwanted-process-name, - Stop the unwanted process, type
$ sudo pkill my-unwanted-process-name,
Lastly, you may want to also Check Ubuntu 12.04 system requirements.
I hope that this helps to start you in the right direction.

you can also use
htop, gives you a nice overview of what's running and you can configure how it is displayed. – steabert Aug 31 '12 at 07:13 -
