Also, allocated size is growing and I don't believe in this statistic:
NAME SIZE ALLOC FREE EXPANDSZ FRAG CAP DEDUP HEALTH ALTROOT
cache - - - - - -
gpt/l2arc 185G 338G 16.0E - 0% 182%
I don't have data with SUCH comressibility on given pool, best
"compression ratio" on one of FSes is 1.30, and is negligible on all
others (it is media files, mostly).
