[TriLUG] a Ferrari in a traffic jam (was: why is it slow?)

[jason watts]

i thank you for your input about defragging. i am more of a windows 
person... mainly because i play alot of games. although, i am working with 
learning linux, thus the server

as far as the defrag, i knew it was a windows thing and i had never seen 
anything like that for linux, but was just wondering if there was something 
similar
