Compress swap pages written to disk

Question

This answer says that zswap decompresses pages before writing them to non-RAM swap.

Is there any way to compress the pages written to disk, ideally with lz4?

I hope to:

• Reduce SSD write wear
• Reduce swap disk allocation
• Speed up swap IO (hopefully fewer blocks are written/read to/from disk)

Answer 1

The only solution I've found is not using a dedicated swap partition and storing the swapfile in a zfs partition.
