Performance questions

Hi

I have 2 different sites with the same aspnet code.
Both are running in their own app pool.

1st one is the important site and performance for this one is more important
than the second one.
Of course in the codes I have some customization routines.

One of those routine shows and assigns url for a hyperlink.
For the important (high traffic) site (site 1) I need to show that link and
for the 2nd site I need to hide that link.

Now the question is:
Should I make this hyperlink visible from the HTML part which will be
suitable for site 1 and hide it from codebehind in the second site?
Is there any performance difference doing the vise versa?

The following is the code I have now:
if (Site1)
{
hyperlink.NavigateUrl = "Default.aspx";
}
else
{
hyperlink.Visible = false;
}

However the following code looks nicer but will it give any performance hit
to site 1?
if (Site1)
{
hyperlink.NavigateUrl = "Default.aspx";
hyperlink.Visible = true;
}

Looking forward for your advise.

A new source for .NET DevelopersI don't think this is kind of code would be the performance bottleneck.
Typically it is either related to database access, or complicated
calculations or processing in the code. Setting one property on a hyperlink
isn't going to make a difference.

I don't think that either of these options will have much of an effect on performance... how often is this code called?

Hi,

I don't really have a problem with the performance and the difference
between them is may be 1/10000000 but I just want to know which one is
faster.
May be in the future this information may help me on 100 show or hide items
in one page where there are tremendous amount of hits to that page.

Well, if you have to set 2 properties instead of 1, then setting 2 will take
longer.

But even with 100 of these controls, you aren't going to see a difference.
This is just changing a variable in an object. That variable is used when
it's time to generate the corresponding HTML. But by setting the property,
you are just changing some local variable to the object.

Again, unless you have tens of thousands of these, this isn't going to make
a difference. I would focus on more likely bottlenecks in terms of
performance.

Performance Testing -WAS

Hi

I am trying to test an ASP .NET application using Microsoft test tool WAS.

There is an option called client as part of the WAS tool. The documentation says that I need to give the ip address of the client machines from which the testing will be done..

Cant I just use one client machine and test my application and simulate cuoncurrent users for a single machine itself?

Thanks
KalpaFor realistic performance testing, it's also recommended that you run the stress testing tool from a separate machine other than the Web server. The actual request generator can be fairly resource intensive while generating the Web requests and this overhead can affect performance of the Web site under max loads. However, even though the documentation states two machines are a requirement you can certainly run WAS on the same machine as the Web server, but don't expect 100% accurate results especially when you're testing at the top end load for the hardware you're running on.

Performing Asynchronous operation

Hi
I have 2 operations to perform one is to upload data and the second is
to generate report. Both take huge time(more than 20 mins and I believe
by that time session would have expired) and hence has to be done
asynchronously.
For uploading data, user will click start button and the asynchronous
operation has to start immediately.
For report generation, user will enter a time when the report has to be
generated(wend date time) and press start button. The asynchronous
operation should start only at this designated time.
How can I do the above 2 operations?
Thanks

Permission problem

Hi
I am trying to download the PDF files from my webserver using ASP.Net.
All my files are stored at F Drive on webserver. Like this F:\Main
Folder\Sub Folder\user folder\files\File1.pdf
I am impersonating the domain user account and downloading the file, It
seems the impersonate is got success.
If I gave full control to that user folder, its allowing me to download the
file.
BUT, If I gave read&execute permisson to that folder, its asking me the
windows username and password window for dowload the file.
My client doesn't need that windows checking. we already given the read &
execute permission to that folder, then why its asking the windows user name
and password window?
any idea please.
thanks
balaIs it possible that a temporary file is being created somewhere and that is
demanding greater permissions?

Permissions Problem

Hi

I have created a facility to allow the user to upload an
image file to the webserver. When the user creates the
image for the first time i.e. the image does not exist
within the directory everything works fine. The problem
occurs if my ASP.NET dll tries to delete the file or
overwrite it?

I assume my app will be using the ASPNET account and I
have ensured that this account has full control over the
directories in question etc.

Anyone any thoughts?

Thanks in advance

AndyWhat is the error?

Whoops!

I have since restarted IIS as well but to no avail??

this is the error generated:-

SORTED!

It seems that under Windows 2003 the process is NOT
running under the ASPNET account but a NETWORK SERVICES
account?

However if this is the case how is it writing the first
file upload successfully to the directory?

weird!

It is now working though, which is nice ;-)

There are only 2 possible reasons why your app might be denied access to the
file:

1. It doesn't have the necessary permission
2. The file is in use by an application and locked.

You can easily determine whetyher it's number 2 or not. If you can delete
the file and the app cannot, the problem is number 1. When a file is locked,
even the Administrator group can't delete it.

If the problem is number 1, re-check your permissions. And remember that
Deny permission always overrides Grant. In other words, if you have granted
the user permission, and somewhere else that permission is explicitly
denied, the permission is not granted.

You may also want to make sure that the account you think ASP.Net is running
under is indeed the account it is running under. To do this, just open up
Task Manger, check the Processes tab. The user account under which your
ASP.Net worker process is running will be displayed.

Hi Andy,

Thank you for posting to the MSDN newsgroups.

I am glad to know that the problem is resolved. You are right that the
default account is the Network_Service account in Windows 2003 Server (IIS
6). If you want to change the account, please refer to the following
article.
