Just wanted to share our experience with using zfs compression on FreeBSD for our rrds.
We’re seen a fantastic 21.41x compression ratio on our 46k rrds stored on a zfs volume compressed with gzip. This means meaning we’re saving 93GB of space by doing this 🙂
The gzip compression is CPU heavy so if you want to use this you need a good amount of CPU available but if your short on IO throughput which tends to be the case when updating this many rrds it also a great way to improve performance.
