Performance Q..

My development environments are ASP.Net and VB.Net and .NetFramework1.1.

I remember reading "using less number of session variables is good for
application performance".

Now instead of using 20 session variables, I can use one session variable
which carries the data for all the 20 variables that I want to keep track.

Is it a good idea? Any documentation on how exactly the sessions variables
are processed and stored in IIS5?

Thanks,

Lalit SinghPerformance generally falls into 2 categories: Processor and Memory.
Anything which saves Processor usage or Memory usage improves performance.
If you can remember that, you can stop relying on opinions you read to
determine what you should do.

Session is memory. Anything which reduces Session size will improve
performance. Combining Session variables into a single object isn't likely
to improve performance, as you aren't changing the size of anything, just
how it is stored. If I put 5 apples in a box, I still have 5 apples. I also
have the box now.

Programming instructions are Processor. If, by putting all of these objects
into a single object enables you to write leaner code, you will improve
performance. For example, using the apples again, taking the apples out of
Session one at a time, I need to write 5 sets of instructions, or a loop
that executes 5 times. If I take the box out, I use only 1 instruction. Of
course, at some point you're going to need to take the apples out of the
box. So, that kind of cancels out the savings there.

But let me get back to my original point: Don't rely on opinions. If you're
really concerned about performance, keep your eye on Memory usage and
Processor usage. Don't concentrate on Session. Concentrate on your whole
app. Look for opportunites to write leaner code, and maximize memory usage.

Permissions Issues with ASPNET Account

For some unexplained reason, I am suddenly unable to browse to a virtual
directory on my laptop. I have a number of sample websites to which I could
happliy browse up until last w. As of Monday, if I browse to any of the
sites, I get an HttpException saying "The directory does not exist or is not
accessible because of security settings." I honestly have not changed
anything at all.
I have checked and re-checked that ASPNET indeed has the three required
permissions on the virtual directories (ie. Read, Read & Execute, and List
Folder Contents). As a workaround, the only way that I am able to currently
browse to the sample websites is I 'upgrade' the access level privilege in
the machine.config as follows:
Go to folder C:\WINNT\Microsoft.NET\Framework\v1.1.4322\CONFIG, and edit the
machine.config file. Find <processModel enable="true" timeout="Infinite"...
and change the username attribute from 'machine' to 'system'. Save the file,
and restart IIS.
I have trawled the internet in the last couple of days, and have discovered
many others have experienced the same problem. For most, it was a matter of
applying the ASPNET account permissions to the virtual folder, but there are
still a number of other people (like myself) for whom this problem persists.
I have even ran aspnet_regiis.exe, but still no joy.

Persist object

Hello all,
I'm in need of some brainstormin help!
We have an object that we use in a number of places, both by User Controls
and Pages. This object is loaded everytime we need to use the piece of
functionality.
Example:
The user logs in and the object is loaded, the user then clicks a link to do
a task and again the object is loaded again.
What is the best way to persist the object? Session, cookie etc as it will
be used alot as the user uses the app.
Also, what are people thoughts about this, and it there any patterns that
may help?
Thanks all,
JonJon,
If it is an aspx or html page and is called with the same parameters or
without any parameters, it will be cached on the client side and will open
very fast. You will have to tell us more about the nature of the object to
hear other suggestions.

Some ramblings,
if the object is loaded from server side state then I suggest making
all your pages (and controls?) extend from a base class (that you
create), this class would extend from System.web.UI.Page,
This class could load the object and set a property, which the derived
classes could access.
If the object is not to big then I'd recomend doing this each page
load, caching the object brings in added complexity,
If its a big object (or static for all users) then cache it, use the
session for user based objects and cache for static objects
In my experience though its best to load the object with each page
request
Eliyahu,
The object is data that is a collection class that we loop through to
create a tree (like Windows). This tree is not only used for navigation, but
also used in UserControls to help the user when carrying out some action,
like copying a file, specifying where to place a file etc.
The data help in the collection class rarely changes, but when we use it, we
always reload it and we were just thinking if that would be a performance
drag?
Thanks,
Jon

Jon,
If the collection is specific to a user session, the best place is the
session.
If it is application-wide, meaning it is the same for all users, a public
static variable will be good. You can also use application's Cache if you
want to be able to control the way how the object persists.

Persist object

Hello all,

I'm in need of some brainstormin help!

We have an object that we use in a number of places, both by User Controls
and Pages. This object is loaded everytime we need to use the piece of
functionality.

Example:

The user logs in and the object is loaded, the user then clicks a link to do
a task and again the object is loaded again.

What is the best way to persist the object? Session, cookie etc as it will
be used alot as the user uses the app.

Also, what are people thoughts about this, and it there any patterns that
may help?

Thanks all,

JonJon,

If it is an aspx or html page and is called with the same parameters or
without any parameters, it will be cached on the client side and will open
very fast. You will have to tell us more about the nature of the object to
hear other suggestions.

Some ramblings,

if the object is loaded from server side state then I suggest making
all your pages (and controls?) extend from a base class (that you
create), this class would extend from System.web.UI.Page,

This class could load the object and set a property, which the derived
classes could access.

If the object is not to big then I'd recomend doing this each page
load, caching the object brings in added complexity,

If its a big object (or static for all users) then cache it, use the
session for user based objects and cache for static objects

In my experience though its best to load the object with each page
request
Eliyahu,

The object is data that is a collection class that we loop through to
create a tree (like Windows). This tree is not only used for navigation, but
also used in UserControls to help the user when carrying out some action,
like copying a file, specifying where to place a file etc.

The data help in the collection class rarely changes, but when we use it, we
always reload it and we were just thinking if that would be a performance
drag?

Thanks,

Jon
