I have one concern with the latest development kernels and that concern
is swapping.
(I am going to check this on a 2.1.88/2.1.40 if this helps, but that
really depends on time at hand which is a scarce resource at the moment)
OK. Lets describe the setup:
Freshly booted system. 128 Mb of RAM and really only 25 MB used at the
time of the test (mostly a netscape and X11). The test:
tar cf - . | cat >/dev/null
In my opinion this test shouldn't force any applications to be swapped
(because the only thing really used by this test is the buffer cache,
which is supposed to take up only free memory). Well the end of the
story is, that I end up with more than 10 Mb of swap space used, and 11
Mb of free memory. Why is buffering preferred to keeping applications in
memory?
