Linux file copy slowness ??

Hi,

We are trying to copy a 15Gig file from one directory to another
(inside same partition) for example:

cp /data/BigFile /data/data/ (Bigfile - being file that is greater
than 15 gig).

It takes about 32 minutes to finish copying. When we do the same
operation on a windows 2003 server it takes almost HALF the time.

I am wondering if this behaviour is normal or something wrong with
system?kernel? etc.

The system is a hefty: Dell 1850 server with Dual Xeons 3.2 ghz (hyper
threaded) with 2 Gig ram, SCSI hard drives 10k rpm.

Also, while the system is copying the file, I don't see any kernel
errors or IO errros and all the time while the sytem is copying this
drive the cpu usage is at 50 Any help is highly appreciated.

Forgot to mention on another post: The file system is EXT3 and OS
-Redhat Enterprise 3

-Parvinder Bhasin
