all right thanks for your answers
Cache dedicated to the kernel would slow the libraries.I am still not convinced. if the Kernel code needs to run in a system
with no dedicated kernel cache, user application code and data can be
evicted from the cache to be brought back later. This will definitely
slowdown the execution of the user application. with dedicated kernel
cache, the content of the user cache is unchanged and hence user
application execution can be resumed without immediate cache Miss. How
can deciated cache to the kernel slow down user applications
Thank you
