Hello Mirko,
I have repeated the new simulation to be sure. I have attached the new and old result so you can take a look at them.
Best regards
Florian

Betreff: AW: [sumo-user] Simulation Time after Windows update
Hi Florian,
just to be sure: You used SUMO v1.18 in both cases? If not: Recently we discovered a bug which would cause SUMO to slow down under Windows due to the localisation overhead. This bug depends on the scenarios and how often a specific code part is called.
Otherwise it will be difficult for us to diagnose as our IT systems are managed and thus have completed the update as well. But we will think about how to prevent such things to go unnoticed.
Best regards
Mirko

Hello all,
I suspect that sumo is slower after an update to windows 22H2.
I have run simulations with the HBEFA model before and after the update.
Before that the simulation time was:
- 616 s
- 539 s
- 3201 s
- 3306 s
After the update:
- 827 s
- 739 s
- 4406 s
- 4506 s
1-4 are different traffic conditions
The remaining settings and conditions were all the same. Sumo version 1.18
Is there any way to get back to the old simulation durations?
A restore to Windows 21H2 is unfortunately not possible.
Many thanks in advance!
Best regards
Florian
