Stackless Python vs. Go

Note: I did a little more research and it turns out that the gc runtime creates one OS thread only, and then adds threads as a way to avoid I/O locks. On the other hand the gccgo runtime maps goroutines and p_threads on a 1 to 1 basis (as of now).

I have been lazily following the Go language project for a while now, when it
was suddenly discussed in this post of “Appunti Digitali” (in italian), that
pointed at this post
on Dalke Scientific.

It really got me that S.Python manages to beat Go so
badly, so I decided to run my own tests on my trusty old IBM X-41 (Pentium-M 1.5

The reason for this strange behaviour was that I did not add the ComboBoxes to the form Control list BEFORE binding the source!
The worst thing of it all is that I have not been able to find any clue about the order in which these two operations whould be done on the MSDN, nor on various developer forums!

So rememeber:

  • First add the controls to your form
  • And only then you can correctly set the DataSource
