New Dell Poweredge T420 Server Running Terribly Slow

We have a Dell Poweredge T420 that we installed in August and it only runs a SQL web app.  About a month ago the app started running terribly slow, so as a last ditch effort to fix the issue I updated the RAID drivers and firmware and also the BIOS.  After that the server ran like it used to.  Now a month later the system is doing the EXACT SAME THING!  There aren't any errors in event ID, and Open Manage indicates nothing is wrong.  There aren't any newer versions of the driver, firmware, or BIOS.  I am at a loss.

Dell Power Edge T420
Windows server 2008 R2 SP1
SQL 2008 R2
Only half memory is being used and the processor is barely being touched.


The only other symptom is that I noticed is that extracting/zipping a file takes quite a long time and that there is a small lag in using the OS.

Has anyone ever seen anything like this?

Turned out to be indexing issue with a custom SQL service...

It's a PERC H710 RAID controller, RAID6 4 hard drives.

May sound a silly question but have you tried rebooting since you presumably did that at the same time you upgraded the firmware.

Yes, I have rebooted twice since the firmware install, the latest was Friday.

When we try zipping or un-zipping a drive it is EXTREMELY slow, 2.7 MB took about 3 minutes.

Presumably the battery status is good which you'd know about anyway since you rebooted to eliminate a Windows problem.

did you test if it runs better from a clean boot?
run msconfig  - in startup tab, click disable all
in services tab - click Hide mS services - then clikc disable all

reboot to test

What about the specs of the server itself?

CPU? Memory? Disks?
SATA or SAS?

Have you installed OpenManage on the server to see if anything is wrong at the hardware level?

Put that on it and lets see what if anything has a yellow/red flag...

You mentioned you did reboot - does it speed up after a reboot at all?

Doesn't make sense that zipping/unzipping speed would be affected by a SQL service.

Can you please detail the solution if you recall to assist other EE members?

I have a PET420 server that was exhibiting the exact same behavior and after updating drivers/firmware - it appears to be running much better.

Based on your comments, I'm worried about it slowing down again in a month or so.

We run SBS 2011
