Subject: [DUG-OFFTOPIC]: NT Speed
>Recently I noticed my machine was getting a bit sluggish. It runs NT4 on a

>the end I wrote a simple program myself (attached).
>
>It simply writes a big file and then reads it (using the unbuffered option
>of CreateFile). The results were very interesting, my disk was running at 2
>MB/s or less.

>The NTFS disk was quite full and fragmented, so I cleared some space and
>eventually got it defragged (not as easy as it sounds :-). The speed went
up
