The reason why your system is EXTEMELY SLOW is that your system got only 256MB RAM. INSUFFICIENT !!!
You need to upgrade your system memory (RAM) from 256 MB up to (at least) 512MB or more (better be 1GB).
You need to check which kind of RAM and speed compatible to your system.
Guess it would be at least DDR-RAM and perhaps speed is DDR-400 or more.
