SeaDAS new l2gen very slow

[melinfr]

Dear Alex,
thanks a lot for your feedback, this is really appreciated.
I am also using l2gen on the command line (from a shell, I tried csh and bash).
The test image I am using is actually ~ twice smaller (7848 lines) because it is cut at 10 deg. North.
With l2gen associated with V2023 (9.6.0-V2023.3), it took 1066 seconds (so similar to your calculation) but 8456'' for V2025 (9.11.0-V2025.1).
At that stage, the only test I still envision is to try on other operating systems. Or if you have other ideas?
Thanks again,
Best,
F.

You could try a different OS.
Also, could you compare the output files produced with the V2023 and V2025 tags? An L2 file has a group named processing controls, which contains all the input parameters and files. These should be the same in both tags.
