Hello

I'm still new in Houdini and I'm still learning, because everything in Houdini Is far better and faster, and because I have quite strong workstation that I would like to use as much of it's power as possible.

but I notice when I for example advect VDBs or when I try to create animation with them by converting a geometry to VDB then make the sim then convert it back to geo or even keep it as it is, the simulation is slow if I rase the resultion of my model or use a 3d scans, so my question is there sort of rules or something like a tutorial for optimising VDB or volumes in general for a faster and better result in simulations ? if so can someone point me where to start ?

Thank you.
