What Should I do?

If anyone can help that will be much appreciated.
I have implemented async socket server & client, functionally both work
well, when connected through loopback, performance is reasonably good. The
issue comes when i run the software over the network while functionally it

Reading msdn.com and several blogs (also on msdn :)) it appears that simple
properties that just get/set a private member are good candidates for
inlining by the JITter.
Does anyone know if inlining occurs across modules? Say I have module A with

Can anyone shed some light on why a web server running ASP.NET with 1GB of
memory works fine, but when I increase the memory to 2GB I constantly get
"Out-of-Memory" errors?
I'm stumped.

I have a tool that generates VB.NET code, compiles it into a DLL in memory
and then executes a method on the class.  I can execute the method on the
class thousands of times per second.  
The generated code is slightly different each time the tool is run, so I

We are developing a large dotnet application, which includes ~ 120
assemblies. (total size of all binaries is ~ 20MB). Our application
also references the following dotnet assemblies: System,System.XML,
System.Windows.Forms, System.Drawing, System.Data,

I have a .NET application written by C#.
It works fine in the most time, but sometimes, once or twice a day, there

I am developing an application that gets a brust of about 1000 or more
packets at same time from different IP addresses.
I have to process each packet and performance is essential. I am using
UDPClient to recieve packets and then using a Delegate function to pass the

DateTime.Ticks is very slow
I use it but it is updated 64 times in a second.
I think performance counter is the fastest counter but I could not use it
for elapsed time. It is complicated.

I have read that Exception Handling is expensive performance wise ( other
than Throw ) , but exactly how ?
Please consider the following example ...
////////////////// Code Block 1 //////////////////////////////////

I need to use high resolution timer. I' ve found that
QueryPerformanceCounter from Kernel32.dll coudl be used for this purpose.
My question is what is this counter for? I know only that it is zero when
starting windows... What does it mean one step for this counter?

Which is better in terms of performance.

ForNext loop (using indexer)
ForEach loop
