sql server dts : Slow DTS server performance

Hi,
I'm running SQL2k sp3 on a dual Xeon w/four drives/arrays
(SCSI)(OS on C:, Logs on E:, tempdb on F:, Data on G:
(500GB)). I have a large DTS package for processing text
files for billing and reporting purposes. The input file
averages 400,000 rows per day and ends up creating a
dozen tables that average 300k rows per file. Various
data is exported and zipped to disk with WinRAR. The
package is either executed manually on the server or
scheduled to run from the server

My problem is that the DTS package runs about 20% more
slowly on the server above than it does on my desktop
workstation (executed locally or as a job), which is a
plain old 1.8 P4 with a standard drive. When I check the
process both processors are running around 80%.

Another example is a single column update on a 1 million
row table (again executed on the server) with a single
join to an indexed table with 8,000 rows. This update
took over 2 1/2 hours.

I'm looking for advice and hints about how to start
researching theslowness problems.

have you look at your performance counters ?
First you must identify the problem:
* CPU
* HD (Avg disk queue length)
* Memory

I've the same type of problem with a "big" server, but I've no time to find
the source of the problem.
I suspect the RAID 5 and the drives to be the problem in my case.

What is the result if you export your data to another computer instead-of
the local drive?
Where is your export folder actually?
