Subject: Paging out sleepy processes?
Date: Wed, 20 Oct 1999 04:24:04 -0400 [thread overview]
Message-ID: <380D7C24.AA10E463@mandrakesoft.com> (raw)
I have a simple app that I run locally that allocates and randomly
dirties a lot of memory all at once, with the intention of forcing Linux
to swap out processes.
How possible/reasonable would it be to add a feature which will swap out
processes that have been asleep for a long time?
IMHO this behavior would default to off, but can be enabled by
specifying the age at which the system should attempt to swap out
processes:
# tell kernel to swap out processes which have been asleep
# longer than N seconds
echo 7200 > /proc/sys/vm/min_sleepy_swap
Is there a way to do this already?
Regards,
Jeff
