CPU usage comparison for MS SQL Server 2000

kim
Hi All,

I had two Window NT 4.0 Server, say A and B... We recently upgraded
from MS SQL Server 6.5 to MS SQL Server 2000 on Computer A, and for
Computer B, I installed SQL Server 2000 from scratch. These two have a
same RAM(512MB) and CPU speed...so the setup for hardware is almost
identical...

For server A, there are around 10 connection to this SQL Server...
For server B, there are also around 10 connection to this SQL
Server...

The database for SQL Server B is a copy from SQL Server A.... I
restored the database on SQL Server B from the backup dump of Server
A...

We have a store procedure called usp_GetMemo(ID Interger) ... we feed
ID number to this store procedure and return its return Description...
this table has ID column and it's Non-Cluster index, allow the
duplicate row... there are 1.7 million records for this table...

Here is problem... whenever i execute more than 100 times for this
store procedure(usp_GetMemo(ID)) continuously, the CPU usage of
Computer A is 3 times bigger than computer B....

I did run the command "DBCC DBReindex" , "Update Statistics" for this
table on computer A, but did not make any difference...

Keep in mind that Computer A has been upgraded to SQL server 2000
while Computer B installed from scratch... would that make difference
somehow?? Before the upgrading, the CPU usage of computer A is the
same as Computer B...

Any help will be really appreciated,
Thanks alot,

Have you checked that the database compatibility level of the upgraded
database is set to 80, not 65? See sp_dbcmptlvl in Books Online.

On top of that, never do an in-place upgrade, you leave sooo many things
behind when you do that.

There are many things to consider -

Hard drive arrays and cache - Are they the same?

Drive fragmentation? Did you defrag both servers?

Users, not just DB users, but total users on both systems - are they the
same?

Did you set the SQL memory at 400MB fixed or did you allow it to use as
much as it wants? Never allow it to do it on it's own, make sure that
you leave 128MB for the OS to use.

Did you run the maintenance plan on both systems?

Kim,
I don't think the upgrade is the problem. I think the problem is the
drives in server A. If they are identical drives, configured in the same
format as server B, then try defragging the drive(s) on server A. They have
probably been in use for a while and are probably very fragmented. Make
sure you bring down the database before defragging. Also, recommend you use
a 3rd party defragger like Norton speed disk as the defragger that comes
with Windows doesn't do as good a job.
Hope this helps,
Best regards,

Hi,

Thanks a lot for your respond....

For the Hard drive arrays and cache,How can i check it.. i'm no expert
in hardware stub..

Yeah, for Server A has not been defrag for a while.. Yes, I should do
fragmentation on it....

Thanks a lot
