People who use computer, will get experience decreased computer performance. This is natural, like a motor, not more and more comfortable and it's time to service. Required tools used for service. For Ubuntu users, I have an alternative tool to speed up the performance of a new pc so as to reinstall. Tool that I use is Janitor's in Ubuntu Tweak.

For those who do not have the application, immediately install Ubuntu Tweak. Ubuntu tweak has many features that are useful to perform a custom operating system Ubuntu. After installation, go straight to Ubuntu Tweak

One feature of Ubuntu Tweak that can be used to accelerate the performance of the laptop / computer is the Janitor. Janitor is a useful feature to delete not yet required files that exist on your computer / laptop. Some of the files that are deleted will require root access like linux header. To do this simply select the menu or start Janitor Janitor.

Janitor features will be demonstrated on what needs to be removed complete with file sizes that need. Starting from the browser cache, package unneeded, unused header and thumbnail.

Clean PC with Ubuntu Tweak Janitor

After selected that will be clean, press clean button at the bottom right. Wait until clean process is completed, it will probably take a few minutes if necessary to uninstall the linux header as I did. When all was cleared, there may be some files are automatically created again, but at least have a much smaller size than the previous one.

Computer is clean

Try restarting your PC / Laptop after clean all uneeded package, then feel the difference in speed. For the internet will probably be a little slow in opening web pages, because its cache also removed using ubuntu tweak. But overall there is a change a little faster, though not very significant.

At least 1 month to do the above steps, to keep the filesystem is not full. So there is no occurrence can not login to the desktop because the filesystem is full. As I've experienced.

Actually there are many tools that can be used to 'clean up' file not important, but because there is ubuntu tweak your laptop, so no need to install other software. Maybe anyone wants to share what software is used to clean up PC like Ubuntu Tweak Janitor?
