Knoppix on USB stick sometimes runs very slow
I have knoppix 7.2 installed on a 34 GB USB stick (I used the DVD iso for this) . When first used this worked perfectly and fast. Now it often runs extremely slowly. This is not an internet access problem as even the word processor runs slow when the problem is present. I have 4 GB of Ram so don't think this is a problem. I have a 4 core cpu 2.50 gigahertz Intel Core2 Quad Q8300
64 kilobyte primary memory cache
2048 kilobyte secondary memory cache
Sometimes there is a problem, sometimes not.
Thanks for any help
