Performance Questions

Hello, I have a couple questions.
1) Are there issues with tables where the row-size is so large, that insert
performance is degraded? For example, if the row-size exceeds some page
size, this may affect insert performance.
2) Are there issues with stored procedure performance based on the number of
parameters being passed to the stored procedure? We use a stored procedure
to insert data, and if we have a lot of columns in a table, we would be
passing the stored procedure a lot of parameters.Comments Inline

Row-size cannot exceed page-size, except for BLOB data which is stored away
from the main row-oriented data. Page splits are more likely with a large
row size and that may have a performance impact.

I see that all the time with .NET clients 'under the covers'. I haven't
noticed any problems.

Performance problems when running trhough Com+ and DTC

Hi everyone,
we have a performance problem when running a relatively heavy INSERT
statement from a COM+ application against SQL Server 2005 (SP1). The query
takes up all CPU resources (4 CPUs) on the database server while processing
(about 15 minutes) and the database server does not respond to other
queries. The general response from the database server computer is also
poor, including its desktop and other user interactions.
When running the same statement from Managerment Studio, it takes about same
time to complete, but it only takes up 1 CPU and other queries can run at
the same time.
This happens only for some queries. A minor change to the SELECT-part of the
query may make the problem go away.
The SQL Server database is a clustered 64 bit installation. The SQL Server
has SP1 installed, but not SP2. Is it likely that this issue is fixed in
SP2.
Thanks in advance.You didn't post the statement so it is hard to say but you can either set
the MAXDOP at the server level or specify a hint inthe query to limit the
number of CPU's a single action uses.

Depending on the particulars, the query might run a bit longer without
parallelism but will keep more CPU resources available to satisfy
concurrent queries. You might also consider changing the 'max degree of
parallelism' config option to less than the number of total processors:
EXEC sp_configure 'max degree of parallelism', 3
RECONFIGURE

Parallel plans can be an indication that query/index tuning is needed.
Examine the execution plans of parallel queries to see if improvement is
possible.

However, I am very interesting in knowing if there is a logical explanation
to why SQL Server processes uses totally different CPU resources when
running the statement from COM+ in a DTC transaction compared to running it
from Management Studio.

For optimal performance of multi-processor installations, we recommend that
the MAXDOP setting remain equal to the number of physical processors that are
being used. For example, if the system is configured for two physical
processors and four logical processors, MAXDOP should be set to 2.
Any thoughts

number of factors. So even if one time it uses all the procs it can easily
use just one the next time around. But in this case I feel it is related to
how it is being called and something called parameter sniffing. You can get
two very different plans if they are not called identically and evaluate to
the same datatypes etc. Again it would help to see the real statement.

I believe COM+ often sets isolation level to repeatable read, which
could explain the situation - management studio doesn't do that.

Then I guess I would ask, are you *sure* that when you run it through
COM+, nothing else is executing? You're running an INSERT statement,
does COM+ get the exact string you use in the MS or does it do a
prepared statement or somesuch? Have you run profiler to be clear on
this?
The COM+ connections might also prep with other random settings that
could be factors. Do they return exactly the same results either way?
You could use profiler to display the plans from executing from either
side, it wouldn't tell you *why* exactly, but it might give more
hints.

Performance problems when running through Com+ and DTC

We have a performance problem when running a relatively heavy INSERT
statement from a COM+ application against SQL Server 2005 (SP1). The query
takes up all CPU resources (4 CPUs) on the database server while processing
(about 15 minutes) and the database server does not respond to other
queries. The general response from the database server computer is also
poor, including its desktop and other user interactions.

When running the same statement from Managerment Studio, it takes about same
time to complete, but it only takes up 1 CPU and other queries can run at
the same time.

This happens only for some queries. A minor change to the SELECT-part of the
query may make the problem go away.

The SQL Server database is a clustered 64 bit installation. The SQL Server
has SP1 installed, but not SP2. Is it likely that this issue is fixed in
SP2?

More information: we are running in a DTC transaction from COM+. The database are using the read committed snapshot option.

Thanks in advance.

You should probably post your table schema (including indexes), and the query you are trying to run. As I recall, COM+ uses a fairly high transaction isolation level by default, so you might be seeing more locking/blocking because of that.

You might try adding OPTION (MAXDOP1) to the end of the query, and see if the query only uses one CPU.

Performance Problems

Hello,

i measure times for a delete, insert and select in a database with a c# program (.net). If i measure times for delete 5.000 data records I get very good times but if I delete 100 data records in a other database I get very bad times.

Example:

Statement: Delete from xy where id =1;

data rows delete : Time:
100 73.045
500 332.238
1000 636.075
5000 36.082
50000 308.774

The same time jumps I get for a select. But only for this big select:

for exmaple:

Select id, (Select name from Gemeinden inner join Hochschulen where distance>=Hochschulen.entfernung and distance <Hochschulen.entfernung ), (Select name from H?user inner join Hochschulen where distance>=Hochschulen.entfernung and distance <Hochschulen.entfernung ) from Hochulen inner Join Uni on Hochschulen.id=Uni.id...

What is the reason for this big time jump? If i update the statistic I get better times for a delete but not for this big select.

Can I change I size of a page (8KB)?

I hope somebody can help my!!

(I use MS SQL Server 2005)

Greeting finchen

The page size is fixed so you cannot change it from 8KB and there is no reason why you would want to either.

What is the query plan of these queries? Have you checked the missing indexes dmv?

Is this too much?

please help me

|||The query with good times create or use a worktable (Index Spool), is this perhaps the reason why I get so good times. Could this adulterate the times?|||

Have you noticed the following missing index warnings:

For the third plan:

<MissingIndexes>
<MissingIndexGroup Impact="85.9117">
<MissingIndex Database="[Perform_Clustern_PODS_100]" Schema="[dbo]" Table="[ILI_DATA]">
<ColumnGroup Usage="EQUALITY">
<Column Name="[ILI_CLUSTER_ID]" ColumnId="57" />
<Column Name="[ILI_CLUSTER_GUID]" ColumnId="58" />
</ColumnGroup>
</MissingIndex>
</MissingIndexGroup>
</MissingIndexes>

For the first plan:

<MissingIndexes>
<MissingIndexGroup Impact="57.3934">
<MissingIndex Database="[Perform_Clustern_PODS_100]" Schema="[dbo]" Table="[ILI_DATA]">
<ColumnGroup Usage="EQUALITY">
<Column Name="[ILI_INSPECTION_ID]" ColumnId="61" />
</ColumnGroup>
<ColumnGroup Usage="INCLUDE">
<Column Name="[ILI_DATA_ID]" ColumnId="1" />
<Column Name="[EVENT_ID]" ColumnId="3" />
<Column Name="[LENGTH]" ColumnId="21" />
<Column Name="[WIDTH]" ColumnId="22" />
<Column Name="[ORIENTATION_DEG]" ColumnId="23" />
<Column Name="[NOMINAL_WALL_THICKNESS]" ColumnId="33" />
<Column Name="[PIPE_SMYS]" ColumnId="34" />
<Column Name="[B31G_MAOP]" ColumnId="35" />
</ColumnGroup>
</MissingIndex>
</MissingIndexGroup>
</MissingIndexes>

Now I wouldn't blindly create these indexes (especially the second one is quite large but it might make sense depending on your specific situation). I would try to create the first one to start with anyway.

|||I think that is not the problem, sometimes he messing a index and sometomes he don't missing the index in the database with the bad times. Can there still be present other reasons? Do the execution plan use only the statistics to build the best plan? Are the four plans are very different ?|||

The query optimizer takes into account a lot of factors to create a query plan. Statistics is one the aspects it takes into account.

But nevertheless, bad query may become good queries with the right indexes.
