Dear support,
I am experiencing something that's never happened before, i.e., l2gen is now excruciatingly slow (with very little CPU capacity used, ~1%). This has happened since I installed V2025.1, while the previously installed l2gen, associated with V2023.3, is running fine (with close to 100% CPU). I noticed that the new l2gen versions are 30% bigger but this is not an explanation. Would you see a reason for this? This is deeply worrying as my current installation is useless. Thanks a lot in advance for any help,
Best, F.

Can you let's us know what mission you are processing?

Also if you run l2gen from the command line, is it also at the command line?

Dear support,
thanks a lot for the reply! I am using l2gen exclusively from the command line (with default options), and so far I've noticed problems with Sentinel-3A and MODIS-A. I have seen that l2gen has taken some weight between the 2 versions. However, the screen outputs appear to be the same (so it does not seem that the new version does something weird). Does the new version access resources on the internet (like your web site) while processing?
Thanks for any suggestion,
Best, F.

What system are you running on?
l2gen does not get anything from the network.

Dear Support,
sorry for the slow reply. Our machines have Xeon CPUs running RHEL 8.10 as OS. When I source SeaDAS to V2023.3, l2gen goes fast, while if it is V2025.1, it is very slow. Do you have an idea of why this could happen?
Thnaks,
Best, F.
