Custom nodes slow down the graph extremely
Hello.
I've just installed some custom SBSAR-nodes via Edit > Preferences > Projects > Library. They appeared in the node list and seem to be ready to work.
However, there is a problem: none of them are cached. Every time I tweak any parameter in a further node, the entire chain up to the custom node is recalculated. The preview update latency increases dramatically, and milliseconds under each node in the chain constantly change.
Could you please explain to me why this happens and how it should be fixed?
Thank you.
