Hi,

and don't forget system's page cache. From my experience:

The files needed to process the first request aren't yet read, so
Linux has to read them from disk (slow).

Then, for the second and further requests, the files are in the page
cache (aka system buffer), so that Linux don't have to read them again
from disk. Access is now super fast.
