Low RAM (64MB or less) will result in computer slowdowns. All of your
applications, Internet included, will run much more slowly because of low RAM. It is recommended that DSL users should have at least
256 MB of RAM.
A low-quality LAN card can cause slowdowns. Upgrading the LAN card can
improve connection speed.
Low hard disk space can cause slowdowns, especially for users who download
large files like videos or music. It is recommended to keep at least 500MB of
hard disk space free when surfing.
