If I was mistaken and Greenbytes will actually put effort into ZFS, that sounda pretty cool... But I wonder, is that a fact, or only wishful thinking?

Small file performance doesn't seem to peak past 50-80mb/sec on reads; but for large files (1GB files) I get W-200MB/s R-200MB/s, both varying up and down by 20GB/S and (16GB files) i get higher reads and writes, up near the 250MB/s range.


audiophil: hate to pollute this thread, but I am very interested in your experience with the RR 4320, and would like to have an offline discussion. Forum doesn't seem to allow PM messages to go through to users other than yourself.

Code: Select all
$ zpool get size tank
NAME    PROPERTY  VALUE   SOURCE
tank    size      16Ti    -


At viewtopic.php?p=4560#p4560 there's much greater than 16 Ti:
