This is especially useful for swapless embedded devices. Also, flash storage typically used in embedded devices suffer from wear-leveling issues - so, its very useful if we can avoid them using as swap device." Explain me because I'm stupid: if we have ram in the first place, why should we swapping and compressing the swap back into ram again? I mean, if you can store the swap in ram, is that you have space, so you didn't even need to swap, no? > PROS: > P1: Much faster > (zero latency and decompression can be 25% as fast as memcpy) > P2: No need for swap partition.

In YOUR country. Please don't generalize. Serious, if you have little ram, it's well possible that you have a low cpu as well. So I don't get the point of this.
