SuperSU/SuperUser slowness... Make it faster?

Hello,

Is there a way to make SuperSU/SuperUser less slow? I mean, on a virgin rom it's already not so fast, but after you install your apps, it can takes minutes before the pop-up asking for root rights comes, if it comes..!! So is there a way to "fix" that? It's a pain, having to reboot sometimes cause of that!

Thanks.
