Make it possible to use zswap (for machines with little RAM)
Closed, WontfixPublic

Description

I'm working with large code bases on a 8GB RAM notebook. It works with a swapfile but the performance impact is noticeable (as in machine close to stops responding at times). I've noticed the task about enabling zram and I'd like to add zswap to be considered as an alternative.

@JoshStrobl zswap and zram are two different technologies. Closing this as a dupe isn't technically correct.

Quoting the zswap wikipedia page:

One of the alternatives to zswap is zram, which provides a similar but still different "swap compressed pages to RAM" mechanism to the Linux kernel.

Can someone point me to a benchmark for zswap?

I'd be glad to benchmark both zram and zswap, how do I go about it?
I could try using the Phoronix Benchmark Suite's memory test, as well real-life tests such as opening and using multiple memory intensive apps at the same time.

I personally think that this could also be a huge boon to low-end Chromebooks as well (and also for old PCs, such as the Dell Inspiron Mini 1018 and the Dell Dimension 4700).

Closing due to lack of inactivity. If someone can provide any meaningful benchmarks, I will look again.

As I had said, I'm willing to test this.
I just need to know how.
