The LZO compression algorithm is very fast. I've used LZO it a few times. http://en.wikipedia.org/wiki/LZO > Note that this is all about in RAM swap.

I had a good experience with compcache about one and half years ago on a IA-32 laptop with 256MB of RAM. By then it was unstable on the ARM so I didn't try it. I would try a small swap (10M?) in RAM with higher priority and the usual SD card swap space. But later... right now upstream is crashing and I still haven't found/looked for the cause :-/
