Without having tried it, I wouldn’t expect much better performance without OSL. A rounded edge shader requires tracing several extra rays, which are costly regardless of the shader language.

If anyone wants to try their luck implementing it directly in Cycles, these modifications made by Chaos Group could be helpful:
