Hi both (Jilliagre and Bakunin) and all,

Thank you so much for your advice and guidance. I can't see where i could have possibly understand more if not here.
Thanks for the link on the introduction to performance tuning and monitoring as well.

It seems like understanding the OS kernel and its working is slowly like a lost trade; people no longer care how it works, people just want things to work..

Thanks for staying around to keep the forum alive, we need you guys around..

=====================================================================

On a side note on ZFS ARC, i do realize it is sucking up RAM and its not reflected as freemem in neither vmstat or sar.

As mentioned my MadeInGermany, i do set a reserve hint -> this kinda set a upper limit on how much ZFS ARC can grow up to.

But how do i know if the amount of memory available and allocated to ZFS ARC is sufficient or not ?

Regards,
Noob
