Feedback on stakepool setup

Just to be sure, this is how I applied the Garbage collector trick and the ZRAM:

GC:

ZRAM:

After applying the ZRAM tutorial I see the following when checking for swap devices:
There are six Zram swaps. I guess one for each processor.

Colonystake_block-producer-node-server02_ZRAM_v001

Using the zramctl command to check the RAM allocation I see the following:
Colonystake_block-producer-node-server02_ZRAM_v002

I noticed the used kB stay’s at 0 and the DATA and COMPR are very low. Is this normal?

I changed the swapiness level to 150% in this file /etc/sysctl.conf by adding vm.swappiness = 150 to push the kernel to swap more often.
