Greetings,

How much memory (RAM) does your system have? My first gut feeling is that 
your machine runs out of physical memory and so it begins to use swap space. 
Hard drive access is much slower compared to RAM. You can determine if this 
idea is valid by typing at a command line:
    $ free -m
And then post the output.

GPML,
