Ok, now I need to test the speed changes here.
I’ve been able to modify my package build script, but I had to leave the lab early tonight.
But I’ll post the new binary packages on tomorrow morning

Here are some other tests with a large image of 9080*11550 pixels and these control lines.
Clang is not always the fastest.

Some show massive gaps, others are close. Worth some investigation. Especially that FFT which I suspected could be faster.
Could be interesting to try compiling with the intel compiler icc. It has always been impressive in term of optimizations.
GIMP plug-in installer for Windows has been updated :

I’m currently trying to compile with the Intel C++ compiler (now named icx), and if that succeeds, I’ll make some test to compare the computation time on some filters.
Bonjour,
I compared 3 versions Win64 compiled with Clang and this command line:
tic fx_dreamsmooth 3,1,1,0.8,0,0.8,1,24,0 toc
TEST clang version 24112910 David / flags = / time = 7mn 50s
TEST clang version 1 samj / flags = -O3 / time = 5mn 45s
TEST clang version 2 samj / flags = -O3 -m64 -march=x86-64-v2 / time = 5mn 53s
:o)
The tests continue with CLANG by compiling GMIC-CLI-3.5.0-pre W64.
Test 1:
The result is quite similar to the test with GIMP 3: 5 minutes 46.621s (5mn 45s for GMIC-QT6-GIMP3)

Test 2 - 4mn 43.468 s:

A version is available for download:

Not about improving the speed of operation, but just a signal that the old problem has returned in the version of 29-11-2024.
