If i remember correctly i measured it makes booting 15 seconds faster. Assuming you enable it early.

The problem is that for compression you want a small vm/page_cluster size like 4kb. (echo 0 > /proc/sys/vm/page-cluster)

But as fallback it hits emmc with 4kb read and writes, which may result in very poor swapping performance. (Im not even sure if you can change the 4kb swap fallback size by altering vm/page-cluster or it is hardcoded)
