I would recommend:
Keep 1 ScriptRuntime/ScriptEngine (as Jimmy mentions you can repeatedly grab the SE off the SR)
Compile the code to a CompiledCode object and repeatedly execute it rather than re-compiling and executing
Create a new ScriptScope for each request
That's basically what the ASP.NET integration for IronPython does.
