Greeting ALL
I understand that L2ARC is still under enhancement. Does any one know if ZFS
can be upgrades to include "Persistent L2ARC", ie. L2ARC will not loose its
contents after system reboot ?

Greeting All
How much data is retrieved by a single ARC hit (Demand & Prefetch lists)
??
Does a single hit means that ZFS will read a total number of bytes equal to
the file system "recordsize" from the RAM ??? More ?? Less ??

Greeting ALL
I am wondering if it is possible to monitor the ZFS ARC cache hits using
DTRACE. In orher words, would be possible to know how many ARC cache hits
have been resulted by a particular application such as firefox ??
Your response is highly appreciated.
