SubjectReading a bunch of file as fast a possible
After searching for kinda-keywords in a locked-in-memory index, I get
a list of 50-100 files out of several hundred thousands I want to read
as fast as possible. I can ensure that the directory structure in hot
in the dcache by re-reading it from time to time, but there isn't
enough memory to lock the documents there. So I'd like to read 50-100
files for which I have the sizes (I put them in the index) and memory
space as fast as possible (less than 0.1s would be great) from
cold-ish cache.

The best way is I think to find a way to give all the requests to the
system and have it sort them optimally at the elevator level. But how
can I do that? Can aio do it, or something else?

OG.
