performance tips

got a friend with sql server 2000 that keeps running slow, he'll restart it and it will run fine for awhile but will gradually get slower.
He's a developer that got DBA thrust upon him.
Wht are some performance tips to help fix this?
thanksHi Mike,
You need to check whether any other applications running
on the same box are competing with SQL Server for memory
and CPU. Sounds he might be having blocking issues too.
With little information you provided its tough to guess
the problem. I suggest your friend to start here..
Great stuff on SQL Server performance tuning.

Performance Problems - HELP, PLEASE

One of my SQL2000 sp3 servers has seems to be responding slower.
Server is Win2000 SP4 running on IBM eServer xSeries 360, dual processors.
There are 58 DBs on the E Drive, and 2 DBs on the C drive, 1 of those
on the C drive is the MASTER, there are no master files on the E drive.
One of the prime functions for this server is Report services.
I began looking around after one of the report writers mentioned that things
were responding slower then in the past, I run this query >
use master
select * From sysdatabases
I get this line for Master>
master 1 0x01 0 24 1090519040 2000-08-06 01:29:12.250 1900-01-01
00:00:00.000 0 80
e:\Program Files\Microsoft SQL Server\MSSQL\data\master.mdf 539
If I use EM and look at Properties for the Master DB it shows the data file
where it should be>
C:\Program Files\Microsoft SQL Server\MSSQL\data\master.mdf
I then ran
use master
dbcc checkdb ('master')
and there were no errors , the final line read like this>
"CHECKDB found 0 allocation errors and 0 consistency errors in database
'master'.
DBCC execution completed. If DBCC printed error messages, contact your
system administrator."
Any and ALL recommendations and suggestions would be most appreciated!!!"msnews.microsoft.com" <breichenbach@.istate.com> wrote in message

The location of the master database, as recorded in a table in the master
database is not necessarily correct. The location of the master database is
specified in the registry on the command line when starting SQL. Master, in
turn, stores the locations of all the other databses.
This is not your problem.
Davud|||> One of the prime functions for this server is Report services.
To expand on David's response, be aware that Reporting Services and SQL
Server will compete for the same resources when both are on the same server.
Large Reports can consume significant CPU and memory resources, contributing
to slowness of both SQL Server and RS.
You need to identify the immediate reason for the slowness (e.g. high CPU,
excessive paging) so that you can more easily identify and correct the
cause. Simply poking around for misconfigured items is like throwing darts
blindfolded.
Hope this helps.

You are absolutle right about throwing darts... I have started researching
how to use performance monitor and SQL profiler to better pin point the
source of the problem. I will post a new request for best resources to
understand these 2 tools..

Performance problem

HI, I have a performance problem with one of my set of packages. They run fine on dev machine but much slower on test server which has twice (8gb) the memory of my dev server (4gb). The first time I run the set of package they execute in less than a minute which is normal. But subsequent executions in same conditions (tables are empty) takes 2-3 minutes. When I restart Sql server 2005, the loading time is back to less than a minute.

I enables the "use awe" for memory beyond 4 gb on test server and while executing, total memory is far beyond the 8gb of test server and on the four available processors, only one seems to be used. Also, deployment on other machines have no problems. We rebuilt the test server (re-installed windows, Sql server 2005, SP1 and patches) with no luck.

I would like to monitor the problem using performance monitor and Sql server profiler, is there some specific counters or trace events that I should focus on? My set of packages (one main package calling several execute package tasks) load approximately 100K lines and they are deployes on file system.

Thank you,
Ccote

Not sure about the cause of your problem. I would sugest to enable package logging and compare execution logs between server and try to identify possible botle necks.

Also there is an interesting document about performance tunning:

Performance of XML vs Database

What is the performance comparison for XML and database?

Using system.IO to read the XML file will be slower than reading data from database , if only read data and not sorting?

The RAM/CPU memory usange will be higher for get data from XML compare to get data from database?

Hi,

You cant say that database is better than XML, its upto the scope of your need,the size of your XML and of much operations you are doing on XML file..

you can use DOM to read and if it is small file just load it at the start and maintain that till the end of the application..

Cheers

happychai:

What is the performance comparison for XML and database?

It depends on the structure of the data. If it is a small file with something like a parent node and a child node with some attributes, and nothing that is relational then XML can be faster.

You will load the XML document once into the DOM and can you XPath to query the data very efficiently.

If you are going to edit data or the data structure is relational that always go for a data base.

thanks for the reply, beside this i want to know is the performance on resouces use.

Is it using system.IO to read the XML using more CPU/Ram resouces than database?

happychai:

Is it using system.IO to read the XML using more CPU/Ram resouces than database?

It all depends on the stucture of the XML and the query involved.

If the file is small and you are only doing a simple parse/xsl then the XML file should be faster but only neglible once the document is loaded into the DOM. Though you should not be basing on performance as a indicator for using XML or a database. With connection pooling and light weight data providers/objects, databases are also very quick.

ok...

thanks for your reply

Performance of stored procedure varies

I have run into an issue that if I use the parameters passed into strored
procedure directly the performance is slower than when i declare local
variable and assign the values passed in the procedure to those local
variable and then use the local variables.
Why is this the case?
