I used the src from the gitlab repo to create a new build as described on the build from source wiki page.  
The render times are really slow compared to the 1.2.2 version installed from the fedora rpms.

Is there something that I should do to make the source package render quicker?

wget “[https://wiki.synfig.org/images/9/98/Ball\_boune\_tutorial\_Spline.sifz](https://wiki.synfig.org/images/9/98/Ball_boune_tutorial_Spline.sifz)”

@tdelov hm… I used “debug” version. With “production” it falls back to 7s.

+1  
Debug version is always a lot slower than production 🙂

OK, Thanks.  
I checked with the \_production build and it renders at comparable speeds.
