[ossrp-control] Re: So, where do you want the project to go?

And in fact, many unmanaged languages are more interpreted than many =
people
think.  VB6, for example, is not entirely compiled, hence the need for a =
VB
runtime which does perform partial interpretation.

Personally, I would imagine most performance problems that your average =
end
user can notice, are mainly down to poor design or coding practice.  =
Because
many complex and common features are directly provided or supported by =
the
CLR and the .NET Framework, you can actually obtain performance benefits
under .NET, which otherwise would have had to be hand cranked before.

Basically, design the system to load and compile the components you =
*know*
will be needed most up front.  Then let the CLR handle it from there, as
long as you don't code humongous modules from which you're only invoking =
a
couple of lines. <smile>  Modularise sensibly.

All the best,

David

Hi Jamal,

Yes, there's a slight performance hit with .Net languages at the moment.
This is to do with the need to compile the code from an intermediate
language to the native instruction set when each element of the program =
is
run for the first time each time the program is run.  So, the =
performance
hit isn't great on elements of the program that are used frequently.  =
There
are ways to get around this, such as ngen, but performance is probably
impacted more by design than whether it's native or intermediate code.
