The /usr/sbin/zram-init currently lacks an option to control the block size for the ext2/ext4/... filesystem on a zram device. This results in RAM filesystems with the default block size of 4096 bytes. This may or may not be optimal, depending on usage.
For example, if you use a zram device to store the browser cache on it, 4096 may be too large a block size. Lots of files in the browser cache are much smaller than 4K (even smaller thgan 1K).
Please add an option to /usr/sbin/zram-init to control block size.
Adding mvaeth to CC for upstream verification, and potential resolutions. Tia Martin! :)
I would mark this a dupe of 610370.
In future, please add feature requests directly upstream on github.
Thanks for the reports, anyway.
