I increased to 4 wait states and tested and performance is not reaching w.r.t time and taking more time to complete the functions. Do I need to increase to 4 wait states?

I have enabled the ART with 4 wait states and there is not much reduced in timing. (Enabled the ART means enabled the prefetch, ICEN and DCEN)I am trying to run from RAM for critical functions, will it improve even ART enabled?

Earlier we worked with F103 and migrating to L475. In F103 for the same clock, they mentioned 2 wait states and but for the same clock in L475 they mentioned 4 wait states. Because of this, my timing is increasing and it is undesired. Even ART enable...

How do copy sections from FLASH to RAM? I am using the scatter file but not the linker script file. Can anybody help in it?

I am using STM32L475 at HCLK 72MHz, at this clock the number of wait states required is 4 but I configured for 2 wait states and ART enabled. At this condition, my controller performance is good w.r.t timing taking.
