The other alternative is to modify ZFS to compress
L2ARC, but that sounds much more complicated to me. Any insights from
ZFS developers would be appreciated.
Compressing the L2ARC data shouldn't be that hard, I had to do something
very similar for adding encryption support to the L2ARC.
When the L2ARC becomes persistent after reboot it should be possible to
have an compressed L2ARC since it should be switching to writing via the
normal ZIO pipeline (zio_write) rather than using zio_write_phys.
