Hi,
I've found some information from CMN600 technical reference manual about SF size as below.
"For best performance, the total SF size should be twice the total exclusive cache size for all RN-Fs. For example, for a 32MB RN-F total cache size, the recommended SF size would be 64MB."
My question is that why we need to set the SF size to be twice the total exclusive cache size for RN-Fs? If SF size only covers the total exclusive cache size of RN-Fs, I think it is Okay. Why we need to cover the excessive cache size?
Thank you!
