Performance of Application

[anandji05]

Hi

I have an application in C# which has running 25 instances at a time.
This application is developed taking .net framework 2.0 and also this is 32
bit application under windows XP. Now I want to upgrade this application
in 64 bit using .net framework 4.0 or above.
So please any one can tell me if i am upgrading this application the performance
of application will increase or not?.

Please give me the details regarding performance issue when upgrading 32 bit
to 64 bit.

Define "The performance of the application". What measure of performance? You will not just magically see drastic performance improvements in most code. If you are memory limited than yes, you can now address far more memory locations (assuming it is physically available). If your new 64-bit machine has 8 cores, your old machine had 2, and you were CPU constrained, then yes you will see a speed up (assuming your code takes advantage of the extra cores), but it has little to nothing to do with 64-bit v 32-bit.

You really need to understand how this stuff works in order to performance tune anything. I suggest you spend some time learning how the machine and operating system you are writing code for actually functions at a low level. If you can't/won't do that than you have little hope of intelligently optimizing anything.
