#### Compatibility issues in virtual machines

When running zram-config in a virtual machine (VM), you may encounter compatibility issues due to the differences in how VMs handle memory and storage compared to physical hardware.
Performance may vary, and certain features might not work as expected.
It is also common for VMs to not have implemented emulation in their kernel for zram.
If you experience issues, it may be better to not use zram-config in your VM environment.
It is recommended to thoroughly test zram-config in your specific VM setup to ensure it meets your needs.


### Performance

LZO-RLE offers the best performance and is probably the best choice, and from kernel 5.1 and onward it is the default.
