Software Updater? When Finished - What to do to clean up old packages?

[awweeks]

Yes my Software Updater is configured to tell me automatically when it is supposed to run.  I have a question:  What needs to be done to clean up after update has happened?  Like old files no longer needed or old packages no longer used?

Reason for asking is my system runs slower and slower after the Software Updater has finished and i thought Linux no longer slowed down like the bloated Windows Operating System.

Please help!

For me it is not normal than Linux was more  slower and slower after the Software Updater.

You can clean old package with Ubuntu tweak in Maintenance Menu of Emmabuntüs 3.
