I need to implement a plugin interface that is isolated and can be loaded
and unloaded at any time. Right now I am usign a second app domain and
calling in to it using remoting. The problem is remoting is way to slow. I
need to pass in a Stream of data a couple hundred times a second. In my
testing calling this method cuts my perfomrance from about 2 million
trasactions an hour to around 500k, which is unexceptable. Are there any
other solutions out there?

Have you tried other IPC methods, like named pipes or even sockets?

I am using AppDomain.CreateInstanceFromAndUnwrap to create a instance of an
object in the second AppDomain. Then I call a method on that loads all the
plugin instances. It ruturns an array of interfaces. Then I call the
methods on those interfaces through the application.

Calling in to these interfaces is what is slowing me down. I don't see
where you can change the comunicatin method when using
CreateInstanceFromAndUnwrap.

I will assume there is no solution and I have to load the plugins in the
main appdomain in order to perform at a respectable level.

I can't belive what little activity this group gets. Most of the issues I
have with .net are related to performance. I guess most people don't car
anymore.

Nope, it's xmas so most people are away. :-)
If remoting is too slow, you are stuck basically. Your programming
requirements either need to be revisited; that is, remove the pluggable
restrictions which would allow you to run in process in the same domain or
compromise on the performance. Cross boundary is always expensive and you
may have run up against a limitation in your current design.
