sudo zfs set compression=gzip-9 mypool or even the compression type: sudo zfs set compression=lz4 mypool and check on the compression level using: sudo zfs get compressratio lz4 is significantly faster than the other options while still performing well; lz4 is the safest choice. ...
# zfs set compression=<algorithm> <dataset> We recommend using thelz4algorithm, because it adds very little CPU overhead. Other algorithms likelzjbandgzip-N, whereNis an integer from1(fastest) to9(best compression ratio), are also available. Depending on the algorithm and how compressible the...
The total activity check time is never allowed to drop below one second. On import the activity check waits a minimum amount of time determined by zfs_multihost_interval * zfs_multihost_import_intervals, or the same product computed on the host which last had the pool imported, whichever ...

To test compression: # Create a filesystem for the test zfs create mypool/comptest # enable compression on it zfs set compression=lz4 mypool/comptest # now copy on some data (compression only applies to new writes) # you could look at the overall compression ratio zfs get all | grep ...

Oracle Solaris 11.3 includes the LZ4 compression algorithm, which has a better compression ratio than LZJB and is generally faster (reduced CPU overhead). Oracle Solaris customers are reporting ZFS compression ratios in the 2x to 18x range, depending on the compressible workload. If you haven't...
