Are these results expected or am I conducting my benchmarks incorrectly: Benchmark: Query on 363,264 records takes Access 27s to run (Over network) ADO.net: 54 seconds (Over network) ASP.NET: 34s (Local on server) The last two have identical VB.net code. All three run the same query on the same DB.

I have a MS SQL Server and 3 client machines, And a program that works on client machines and fetch the data from the MS SQL Server over a 128KBs/64KBs connection speed.
The program works fine but the data fetching and submitting is slow.
I'm asking about any method or idea or technique that can speed up the the access to the MS SQL Server for example database caching or anything like, So that the program can access the database As if it was on the same client machine.
I'm using .net framework 4, vb.net, c#, MS SQL Server 2008 R8, ado.net, Windows 7

View 6 RepliesI have a few questions regarding database speed issues, I want to learn more on this subject. I searched the internet a bit but could not find an answer that satisfied enough me so I thought i try here. I have used adodb for quite a while but never were in the need of doing it the fastest way. That changed a bit.Is there information on the internet or can you provide me with information that illustrates what the cost is of doing a while not .eof loop to populate a dropdownlistbox with a lot of values or using a different approach? what are the faster approaches? I understand it depends on the situation but i am interested in a summary of some ball park figures. Just to illustrate what is better to use in certain situations.

I'm using VS 2010, and I did a project using VB and a database in Access. The problem is that when I try to put that "application" on other computers, sometimes, is not working. I thought it can be because on these computers they don't have access, but on one computer, is running another app which is using Access and there is no Access installed. How can I check if my application requires Access to be installed or not?
Here is a example of how I did the connection:
Public AccessOLEDBConnString= "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=" & myfullpath & ";Jet OLEDB:Database Password=password"

dim conn as Oledb.OledbConnection
dim sql as string
dim ds as Dataset
