How to improve the performance of huge models when loading.

[luxingxiao]

I have a very large model with 788318 objects, and it takes almost 20 seconds to load after importing the model, which is unbearable, how can I optimize the performance?

Hi.

Which version are you using?

Sirius Web 2025.6 includes big performance improvements. In the tests I did myself, loading a project with 1 million semantic elements takes around 3s with this version. For 2 million elements I measured 6.4s to open/load.

Thanks pcdavid. The version I'm using is 2025.4.0, I'll upgrade the version to 2025.6 and test it again.

OK. Let us know if it fixes the issue for you or not. If you still see the same kind of loading times, I'm interested in more details about your use case which would not be improved by what we did.

Also note that Sirius Web 2025.8.0 has just been released today: https://github.com/eclipse-sirius/sirius-web/releases/tag/v2025.8.0
