Performance tuning and measure on MSSQL 2000

Hi

I am trying to design an IO subsystem for my SQL Server and for that I
need to try and predict IO activity on each table in my MSSQL
Database. My idea is to move the hottest tables into special disk
subsystem away from the less hotter tables. So far I have gathered
that we have three tables more hot than the others but I have no
feeling on ratio on how hot each is and how much activity is on the
less hotter tables. I need to predict how many disks I should assign
to each subsystem and so far...
I haven't found a reasonable way to do this.

The only way I found to see read/writes and physical read/writes is on
filelevel. but I've also managed to do a trace in sqlprofiler to get
the logical read and writes per query but since my queries are often
joins I have no way of spliting that IO between the tables included in
the join and no idea on which hit the buffer pool and which didn'nt.
Is there maybe a counter or some way that I have not found?

Any input would be greatly appriciated.

best regards & thanks

I'm not sure if it's possible to do exactly what you want - MSSQL will
probably cache a lot of the data from the 'hot' tables anyway, so the
issue is not so much the physical disk access as how much RAM you
have, and how well MSSQL uses the cache. There are a lot of
performance monitor counters for buffer and cache management you can
use to look at this.

As for the disks, I would start by identifying how much space is
required on disk, then try to use lots of smaller disks instead of
fewer bigger ones for the 'hot' filegroups. Placing the transaction
logs on separate disks would also help, of course.

If you don't have it, get the Microsoft Press book on SQL Server Performance
tuning. Lots of good help here.

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?

Do you want to see the query plan? On the tables are indexes but I dont know if he use the indexes.

|||It could help us if we see the query plan, so go ahead if you wish to show it.

The first plan with 500 data records this is the select:

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.
