[IronPython] concerns about startup time

I've been evaluating IronPython over the last week or so for a project
at work. Much as I love it, I do have one concern: start-up time. My
demo app-much smaller than the actual one will be-takes about 4 seconds
just to load, before doing any work such as building the GUI. This time
will be acceptable in the deployed application, but adds much pain to
the development cycle-I suspect using C# in Visual Studio would yield
faster overall time even with compilation of a changed file.
I've done the obvious optimization of using -X:SaveAssemblies. The above
times were taken after loading the app once with -X:SaveAssemblies, then
running it a second time without that flag. The main file of the app
contains just an import and a function call. All the other code is in
I'm aware of the authenticode issue. I tried to disable the runtime code
check by running caspol -e off. That didn't make any difference.
Any other optimizations you can suggest?
Do you think there is room for improvement in start-up in IP's
implementation, or is the bottleneck in the CLR?
Assuming there is room for improvement, can you give me a sense of the
priority of this issue, and when we can expect to see a difference?
Thanks for your help.
