Re: Kernel VS application file caching

is there any point in implementing file caching at application level?

Probably not much.

Another question is this: is it possible for userlevel applications to tell
kernel not to cache certain files? For example application might want to keep
frequently accesses .html .jpeg files in memory and not cache rarely accessed
huge files, which would evict many other files when loaded into core.

Have a look at madvise(2).
