terrible shader performance with the latest sodium and iris

around 40 to 50 fps with optifine
Around 15 to 25 fps with sodium and iris
(Same settings , same world and everything else is the same)

Shader pack: chocapic13 v7 toaster edition

(This fps difference applies to every shader pack that i have tested)

What is the problem?
