Hi Holger,?
Thanks for the info on the low level operation. I had a feeling that the NanovnaSaver application would be I/O bound, impacting speed.?
As for the 32bit issue, I was thinking Nuitka might be a useful utility but again, you're the expert here so you to decide what's best to use.?
Cheers
Larry

One of the newsletters I receive had an article on malware written in
Python. Part of the discussion revolved around how to get the size of
the windows package down and there were 3 different Python to EXE
utilities presented that are used for non-malware Python to Windows
uses.
One of these is: Nuitka -
Right now, the NanoVNA-Saver EXE application is very large and takes
time to execute. What Nuitka does is to convert Python code to C and
then compile. The resultant application size is a fraction of what
you get with py2exe or pyinstaller and runs much faster.
I doubt. Start up time can be shorter, but most timeconsuming in
the program is serial communication with the devivce. This wouldn't
benefit from such optimization.
GUI-Code is QT so when instantiated, tha code runs as native c++
compiled binaries.
Bigger calculations like averaging and spline interpolation
which uses native c lib with numpy.
Could you try Nuitka on NanovnaSaver to see if it speeds up the
application? I did not look over the entire website but if Nuitka
compiles C, it might be able to generate both 32 and 64 bit
binaries.
The 32bit issue is related to the fact, that i haven't found
a 32bit build env in github actions. It has nothing to do if
a transpiling would take place.
