@ mr.spuratic,

Can you please explain how to reduce swap_usage memory in the system considering active and inactive memory.

Will the command free && sync && echo 3 > /proc/sys/vm/drop_caches && echo "" && free helps in reducing the swap usage?

Thanks JS

    Why do you want to "reduce swap usage", what do you think you'll achieve with that? The only sensible thing to do for reducing swap usage is to either buy more memory or start fewer programs.

Red Hat recommand to avoid 0. Choose 10 or 5 in value not least for swapiness.

Extract of tuning docs RHEL7 : Warning Setting swappiness==0 will very aggressively avoids swapping out, which increase the risk of OOM killing under strong memory and I/O pressure. *
