[IronPython] Performance Issue

[Dino Viehland]

Instead of doing:

            ScriptScope scope = engine.CreateScope();
            Console.WriteLine(DateTime.Now);
            source.Execute(scope);

do:

                source.Compile().Execute()

and your code should then run in an optimized default scope for the code - just like it does at the command line.

I run the script directly from ipy.exe and it basically behaves pretty similar to python.exe (it always took one second more, but I could live with that).  Here is the output:

$ date +%M:%S;./ipy.exe interpolate.py;date +%M:%S
17:36
WARNING: desired starting time (Tue Jan 01 00:00:21 2008) prior to time of first
 data point (Tue Jan 01 00:00:32 2008), current line: 9411
 series: 3D
force==False, exiting..
17:41

So, the problem is on the DLR side.  Any clues?

-------------------------------------------------------------------------
How does python.exe compare directly to ipy.exe?  That is, try running "date +%M:%S;ipy.exe interpolate.py;date +%M:%S" instead of using the DLR hosting APIs.

Thanks,



Dave
