I am developing one Portfolio Management application where there is
single database shared by all the traders.
I have developed web-based application for this. I want to make this
multiuser application.

I'm writing an application for a client.  This is not rocket science.  The
program simply reads a couple of dbs and then does some updates based on
(relatively) simple rules.  However we seem to have a major performance
problem (and things seem to be slowing down).

I am about to start development on a new framework, and contemplating
whether to use datareader to create objects or to use DataSets to create
object.
For a test scenario i created two classes , with each having 8

I am building the application which is writes in C# and needs goog
performance.
I optimalize it in the .NET Framework .NET 1.1. Then I am start using of
.NET beta Framework 2.0 beta 1, than beta 2 and now Release canditate.

I'm building a smart client application which uses Web services. I'd like to
perform load and stress tests on the application. I need to measure
performance under varying user load conditions. I can't seem to find a tool
similar to Application Center Test that I can use to ...

I'm having a difficult time explaining the following behavior:
A. User1 launches EXE (default "Hellow World!" C++.NET Console App) from a
Command Line on Computer1 and "Hello World!" is returned almost immediately.
B. User1 launches same EXE from Command Line on Computer2 and ...

I have a WinForms application that is running into performance problems in a
small number of end user systems. Problems are related to startup speed, and
several grid related operations using a grid component.
The user system is fast (2.0 GHz) and I have no performance problems on ...

We are developed an ASP.NET web application that has just one ASPX page and
loads different user control depending on the Context and user's access
rights.
We are using ACT to perform stress test and here is the issue:

I was testing a quicksort algorithm.
long startTime = DateTime.Now.Ticks; //ticks before sorting begins
q_sort( 0, mElements.Length-1 );
TimeSpan tp =new TimeSpan((DateTime.Now.Ticks - startTime)); //difference of

I'm experiencing this problem
I have a class in an assembly with a single method PerformCalcs()
If I load the assembly in the main AppDomain and call PerformCalcs() the
execution time is aboput 10ms.

I was talking to a PDC representative about my file read performance and how
if I am reading a file in small chunks, it really seems slow and the
Microsoft representative told me to post a sample.
If I use a memory buffer, the performance is acceptable on my Pocket PC, but

Recently I ran across this article
http://arxiv.org/ftp/cs/papers/0502/0502012.pdf by Peter Kukol and Jim Gray
that gave me a taste of the performance offered by un-buffered file IO. The
method outlined requires SafeFileHandle which is only in .net 2 which my

I'm trying to run volume testing on a .NET site using ACT.  We modified the
script per MSDN article (parse the response/encode view state manually).  I
still get authentication failed - invalid viewstate messages.   Any
suggestions?

I have the SystemMonitor ActiveX control on a form and I try to register a custom performance counter.
I expect that after registering the counter with the OS, the user would be able to add it through
this System Monitor ActiveX control on the form.
Yet, the Add dialog of this ...

Is there any general guidance concerning the cost of using custom counters?
My experiments show the overhead to be extremely low, but they may be
distorted by JIT optimization or caching or...
Are there any existing published guidelines on this subject?
