WebCreates virtual block devices called /dev/zramX (X = 0, 1, ...). Pages written to these disks are compressed and stored in memory itself. These disks allow very fast I/O and compression provides good amounts of memory savings. It has several use cases, for example: /tmp storage, use as swap disks and maybe many more. ... WebApr 24, 2014 · The major difference is that all RAM assigned to zram is lost for application and kernel use. It is permanently assigned as swapping space.

WebWhat is it: With this compiled in the kernel (or as a module), Linux can use a remote server as one of its block devices. So every time the client computer wants to read, e.g., /dev/nb0, it sends a request over TCP to the server, which will reply with the data read. This can be used for stations with low disk space (or even diskless) to borrow ...
WebWhen memory pressure is enough that the swap device is called, the memory pages are written to the zram block device instead of a standard disk block device. Because I/O reads and writes to physical RAM are much faster than to a disk drive, zram responds much more quickly than a swap file or partition. In addition, paged memory is compressed ...
