- 512 MB is a bottle neck of the Raspberry Pi zero 2 w
- specially if we use applications which use huge amount of memory such as LibreOffice.
Kajidataonline from Malaysia about LibreOffice on the Raspberry Pi zero:
“So far its can run as a normal function & I am using the zero 2 w which is much more better”
- But it nice to have a tool to optimize this.
- I would recomment to choose DietPi as an OS which is optimized for low Ram consumtion as well.
- The Raspberry Pi zero 2 w would be great device for mobile applications.
- A 10 000 mAh battery pack can run the device for more than 24 hrs.
- And especially for mobile Office the Pinephone still cannot convince us personally.
- The 5.5 inch Pinephone screen is too small for LibreOffice to be usable.
- With the Raspberry Pi zero 2 we we can choose a bigger screen, for instance 7 inch which should be sufficient for LibreOffice.
- Furthermore, recently Pine64 has pulled the Pinephone keyoard from the market which is almost a sabotage of our office mobile project on the Pinephone
ZRAM
- 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 general-purpose RAM disk.
- The two most common uses for zram are for the storage of temporary files (/tmp) and as a swap device.
https://en.wikipedia.org/wiki/Zram
- it can do a lot to perform the speed.
The following video uses the Raspberry Pi zero w 2 with ZRAM
&
shows why you should use ZRAM on your Raspberry Pi:
- The zero 2 w has only 512 MB Ram.
- Zram helps to gain Ram.
- it frees up Ram for other programs to start.
- it can free up to about 100 MB in example which is a lot of the 512 MB of the zero 2 w.
- Zram allows a lot of fine tuning to adapt it to your needs.
- It increases the speed on a Raspberry Pi 4 over all as well.
So to conclude
Zram in principle offers a solution which has many parameters which can be changed to play around with LibreOffice on the Raspberry Pi zero 2 w, to see if we can get it running to work with it satisfyingly. If we are successful, we would have a Raspberry Pi zero 2 w which uses little battery for mobile office applications.
The proof that LibreOffice works on the Raspberry Pi zero 2 w is already there:
So what we discuss here is only for people who want to optimize this setup.
