I come from a long line of hardcore development(15+ years) (x86/68000 ASM,
C/C+ realtime controls and even live streaming). Without knowing
specifically what/where you are trying to improve (performance), below is my
stab at your problem.

Oviously, .NET comes with much overhead. MS have done an amazing job with
the JIT to create native code and improve performance. Nonetheless,
abstraction comes with a price.

Currently, I use .NET 2005 for most of our solutions. Below are some things
you can look at.

1. Indentify your bottle neck and improve it (spot check).
2. Minimize reflection usage.
3. Use threadpool instead of launching your own thread when multithreading.
4. When multi-threading consider context switching when determining number
of threads.

What I've found is that most performance problems are usually confined to
small section of codes. Identify those and you should be able to resolve
most if not all of your problems.

Good luck.

Hi Morgan,

I too have a VB5/VB6 background, but the last 3 years I have spent most of
my time programming in VB.NET, and except for the loading of Forms, which
seems to be (much) slower, my experience is that the overall performance of
.NET applications is much better than VB6.  

Of course I cannot tell you what the problem is in your application, but
sometimes what I have done to improve the user experience for slowly loading
forms, is to just display the form without loading data in the Form_Load
event, but start a timer instead (20 milliseconds for example) and then load
the data when the timer elapses. This gives .NET plenty of time to draw the
form faster and it looks nicer.  

Hope this helps,

Joris

Where are you getting performance problems? Only thing I've experienced is
that graphics rendering is slow. Everything else seems to be just as quick
as in plain Win32 code.

That graphics is slow is because a bunch of stuff in .NET uses GDI+ and it
doesn't support hardware acceleration (yet). Hopefully that will be
supported in the near future.
