it’s the variable to define how aggressive the kernel will swap memory pages.
higher values will increase agressiveness, lower values decrease the amount of swap.
please also check kernel documentation,
for example, $L4T_Sources/r32.5/Linux_for_Tegra/source/public/kernel/kernel-4.9/Documentation/sysctl/vm.txt
Thank you for the reply - I know the purpose of the variable just asking if anyone has seen issues with Jetson Nano devices after setting it to 1 and what does NVidia recommend. Our desire is to discourage the kernel to put processes into swap memory as much as possible while still having swap enabled and setting the value to 1 would do this.
