Swap but better it behave mostly like actual ram and fast too, not as fast as actual ram but still way faster than swap I can open 5 browser tabs one of them playing a video while compiling a software I don’t feel my system slow down at all
It’s the opposite actually, in terms of implementation Zram is a hack, but it does have it’s use case when your system load doesn’t far exceed your total RAM, on the other hand swap is tightly integrated into the system and it’s on it’s way to implement “Virtual Swap” which is effectively Zram but not a hack, making it like a hundred times better, see This blogpost for a detailed explanation
zram, formerly called compcache, is a Linux kernel module for creating a compressed block device in RAM, i.e. a RAM disk with on-the-fly disk compression. The block device created with zram can then be used for swap or as a general-purpose RAM disk. The two most common uses for zram are for the storage of temporary files (/tmp) and as a swap device.
What is zram?

I always confuse ZRAM and ZSwap. From my understanding ZRAM is the better one and Zswap is kinda outmoded.
It turns into a rabbit hole every time I gotta reference it! Lol
It’s a Linux feature to compress some of your memory and then store it in a RAM disk. For systems with limited memory, it makes it go further.
