Set compression=lz4 on your pools' root datasets so that all datasets inherit it unless you have a reason not to enable it. Userland tests of LZ4 compression of incompressible data in a single thread has shown that it can process 10GB/sec, so it is unlikely to be a bottleneck even on incompressible data. The reduction in IO from LZ4 will typically be a performance win. | Set compression=lz4 on your pools' root datasets so that all datasets inherit it unless you have a reason not to enable it.
