I would like to submit a patch to fix the performance problem. The
simplest solution is to remove the check. Even in the situation where an
application does not read in PAGE_SIZE multiples as described above, if
the page is accessed frequently it should remain in the cache. However, I

Hi,
Hi, I am encountering a performance problem, which I have tracked into the
Linux kernel. The problem occurs with my experimental web server that uses
sendfile to repeatedly transmit files. The files are based on the static
