quick overhead sizing for DDT and L2ARC
Two related questions:
- given an existing pool with dedup''d data, how can I find the
current size of the DDT? I presume some zdb work to find and dump the
relevant object, but what specifically?
- what''s the expansion ratio for the memory overhead of L2ARC entries?
If I know my DDT can fit on a ssd of size X, that''s good - but how
much RAM do I need
