DS218+ DSM 6.2.2-24922-4

After reading many forum’s and posts.
At the moment sysctl -w var , don’t work on my nas.

sysctl -a => show all key’s

The tweaks i did

- create a boot-up rule at scheduler
- add
sleep 90
sysctl vm.swappiness=5
sysctl vm.dirty_background_ratio=5
sysctl vm.dirty_ratio=10
sysctl vm.overcommit_memory=0
sysctl vm.vfs_cache_pressure=50

- save
- reboot nas

Things that i see
- Better response
- Faster data transfer with rsync, at the moment 1 sec / GB

Watch out with ‘overcommit_memory’
Pl read the guide on www for each key you change
So ist this proven to work as expected, I mean the tweaking tips above? Will those settings have some side effects?
No problem for me so far, with my packages,....
On my way there will not be writhing to any var so if it not do the job for you just delete the rule , and you have it back like before.
just watch out with setting the values to high or to low.

Never set swappines to 0 , never do that
