Can anyone explain the benefit using dmamux feature and how it improve parallel peripheral performance between STM32L4 with and without dmamux?

dmamux provides flexibility in connecting peripherals with DMA controller. Older versions of STM32 had it fixed.

I was not designed to improve the performance, but to provide more flexibility. But if you have periherals heavily using DMA you can connect to them to different ones reducing the probability of conflicts.
In some STM32 uCs you can chain DMA requests as well.
