Processor is overuse. Please Help Me

[webmaster.91]

Hello, my device is sm-c9000. I made root my device. The knox value of my device is 0 × 1. Samsung knox devices with 0 × 1 devices slow down the phone and shorten its lifespan by enabling the processor to function even when the processor is not used. As a workaround, we can install a special kernel. Does your device have a suitable kernel? SM-C9000 7.1.1 Custom Rom Please help. My English is bad so i am sorry. Please help me
