SQL Server :: How To Increase The Performance Of The Select Query Fetching Data From Huge Temp Table
Jan 25, 2011I have one Store Procedure that generating report ..
For storing the data there , i used many temp. tables. There is many Select Query , little less insert and delete query.
Now if there is huge data around 1 lac in temp table my select query taking to much time and also may be insert and delete query
I added Primary key to all auto Increment Field in temp table. Also defined Clustered index on that primary key as unique Clustered index to improve the performance .
But there is not so much improvement in case of huge temp table.
Right now the whole Store Procedure is taking time to complete around 1.5 days or around 30 hours ..
So i want to increase the performance as much that it completes on nearly 3-4 hours.
Better Performance To Query The DB Or Cache Small Result Sets?
Mar 14, 2011Say I need to populate 4 or 5 dropdowns w/ items from a database. Each drop down will have < 15 items in it. These items almost never change.
Now I could query the DB each time the page is accessed or I could grab the values from a custom class that would check to see if they already exist in ASP.Net's cache and only if they don't query the DB to update the cache.
It's trivial for me to write but I'm unsure if the performace would be better or not. I think it would be (although not likely anything huge).
DataSource Controls :: Test The Performance Of When The Query Is Included Directly In The SqlDataSource?
Feb 16, 2011I have a query that I want to test the performance of when the query is included directly in the SqlDataSource versus when I call a stored procedure. Does anyone have suggestions on how I would be able to closely watch the actual steps here? I was thinking of turning on tracing and adding Trace.Write for each of the events that fire along the way. This doesn't seem efficient and I wanted to see if there was a better approach.

Sep 20, 2010I have developed a website in asp.net framework 2 . This website is being hosted in two different servers without any change in code. My issue is about the performance of these 2 sites. One website is taking much time for inserting datas to the DB (SQL server 2005). 2 websites are having different DB server.
I think the issue is for the DB server. How can we rectify the DB performance while insertion and Is there any other cause for this permance issue?
DataSource Controls :: LINQ Performance Application Performance Is Not Up To Par?
Apr 29, 2010I am not sure if this is the right forum. I can not find a forum for LINQ.
I am working on an application using LINQ. Application performance is not up to par and my tests show that it is LINQ queries that are slow. I was wondering if anybody can recommend where I can find an article about optimizing LINQ performance maybe by compilation or other methods.

I have a simple SqlCE database one table consisting of 4 columns (specialvalue, name, state)

This code works as expected but I would like to increase the performance since it takes over 30 sec to complete.

Configuration :: Folder Size On Hosting Server Affect Performance?
Dec 14, 2010we host the web application on a server and the structure is..
Root
Module1
page1.aspx
Module2
page4.aspx
Temp
archivedImages
image1 image2
The temp folder size is increased every month as we manually add images.
Except the Temp folder every page is requested from the browser...
We dont use the Temp folder for any other purpose other than archive.
Does this affect the performance of the web application i.e. constant size increase?
how different would it be if we moved the temp to some other location out of the Root?
SQL Server :: Vastly Different Performance Of Table Update On Similar Machines?
Oct 21, 2010Two machines. One a little faster than the other. The slow one runs windows xp, visual webdeveloper express 2010, sql server 2008. The fast one runs windows server 2008, visual wev developer express 2010, sql server 2008.The code in queston involves an automatically generated update function in one of the table adapters, called 'adapter'. Our C# code generates a data table called 'table', with which we update our 'datatable' in the table adapter.
The table has about 100 entries.We then update our datatable in the .xsd file by calling.
int rowsaffected = adapater.Update(table);//this is the line that takes long on fast computer return rowsaffected > 0;//since function returns a bool On the slow machine this line of code takes a few milliseconds.One the fast machine it takes 5 seconds.These results are consistent. It has nothing to do with one machine being busy, the other idle.
What could be the reason and how could it be solved? How can the same code, on the same platform, on a faster machine take 500 times longer than on a slower machine?

Configuration :: Trigger IE9 To Render In Compatibility Mode Negatively Affect Performance On The Server?
Mar 17, 2011Would adding "X-UA-Compatible: IE=EmulateIE7" as an http header to trigger IE9 to render in compatibility mode negatively affect performance on the server? I made the change today, adding it, but now some areas of our site are behaving sluggishly, though we did have a large number of changes come in overnight. I know that we can't single out this as the problem, but my boss seems to think it is.
