Linux may perform a swap out on the following occasions:
By a kernel thread denoted as
kswapdthat is activated periodically whenever the number of free page frames falls below a predefined threshold.When a memory request to the buddy system cannot be satisfied because the number of free page frames would fall below a predefined threshold.
I read the above in a book. I did not find what is parameter for determining the interval of the kswapd. Is there a way to configure the swapping parameters when kernel starts?
