Web Application and Memory

[fabrice]

Hello

I m testing my application based on the framework 1.1 with few users.
I m worried about the memory of my server. I can notice a terrifying
increase of memoring using by my application server.
For example, before start application, the memory using is about 280mo.

After starting the application and 10 minutes of utilisation by 10 users....
the memory has grown to 480mo !!!

I don't understand why. I have try to be clean in my code (vb.net) and
liberate all my object as soon as i can by the nothing and dispose codes.

for example in my code :

'dispose of the Dataset/adaptater objects
myDataSet.Dispose()
myDataSet=Nothing
myAdapter.Dispose()
myAdapter=Nothing

or
'dispose command object
objCmd.Dispose()
objCmd = Nothing

or for the variable :

var1=Nothing


So do i have made a mistake or forgotten something ?
Is it normal to see this situation of the memory ? Does this increase will
stop one day ???

Thanks for your help

Hello Fabrice,

What is kind of app - Winforms or WebForms?
As I understand u use DataSet, right?
What's the size of selecting data?
if each user select 5 megabites of data x 10 user x number of requests +
time when data will be GCedd thus u can get such memmory using

For example in case of using DataSet in ASP.net memory consumption of data
is increased in 4 times. But this is a specific of ASP.net
