Zswap enabled by default - Could give a bit more reliability with more tabs #51

Add these to the cmdline.txt when installing.

zswap.enabled=1 zswap.compressor=lz4 zswap.zpool=z3fold

This will allow compressable objects to be compressed and stored compressed in ram. On a raspberry pi 3, it shouldn't effect performance much at all. It's actually recommended by Ubuntu. See this:

I'm going to try it to see if my once a day reboot will still be ok. Right now I have a video file within a website and it doesn't last the day right now.

Here's some more reading. https://ikarus.sg/using-zram-to-get-more-out-of-your-raspberry-pi/ This one was very informative.

Ok, so enabling it on a 4GB pi 3 immediately makes it more responsive. I did the top command.

zswap.enabled=1 zswap.compressor=lz4 zswap.zpool=z3fold
