We run it on ZFS with compression and it makes a massive difference
to performance :)
While rrd's are binary until they are full, which takes years then
there's a massive space saving to be had, we see a compressionratio
of 8.05x and a refcompressratio or 8.15x with lzjb.
If your running 10 I'd recommend trying lz4 which is significantly
quicker in all regards.
