 Swap is the process of moving pages of memory to a designated part of the hard disk, freeing up space when needed. Swap can be used to alleviate problems with low-memory environments.
-An alternative is to use RAM compression with zram.
+A modern alternative to slow swap partitions is to use RAM compression with zram.
 
-By default Flatcar Container Linux does not include a partition for swap, however one can configure their system to have swap, either by including a dedicated partition for it or creating a swapfile.
+By default Flatcar Container Linux does not include a partition for swap nor a zram configuration, however one can configure their system to have swap, either by including a dedicated partition for it, creating a swapfile, or setting up zram.
+
+## Using zram
+
+With zram a virtual `/dev/zram0` device acts as swap space which lives compressed in memory.
+One can activate zram by creating a `[zram0]` section in `/etc/systemd/zram-generator.conf`.
+Here are Butane config (YAML) that creates the file:
+
+```yaml
+variant: flatcar
+version: 1.0.0
+storage:
+  files:
+    - path: /etc/systemd/zram-generator.conf
+      contents:
+        inline: |
+          [zram0]
+```
+
+You can tweak the size by using the minimum of either 8 GB if one has a lot of RAM or the size of the RAM, e.g., 1 GB, by setting `zram-size`:
+
+```yaml
+variant: flatcar
+version: 1.0.0
+storage:
+  files:
+    - path: /etc/systemd/zram-generator.conf
+      contents:
+        inline: |
+          [zram0]
+          zram-size = min(ram, 8192)
+```
+
+Allocating a compressed RAM section that can hold an amount up to the size of the RAM itself works well because most RAM contents compress very well.
+
+After a reboot you can check the results:
+
+```shell
+$ zramctl
+NAME       ALGORITHM DISKSIZE DATA COMPR TOTAL STREAMS MOUNTPOINT
+/dev/zram0 lzo-rle         1G   4K   74B   12K       8 [SWAP]
+```
