I enabled Caffeine to disable suspend.
I realize the difference between hibernate and suspend in a way the system manages swap.
I use a low memory (4GB) laptop.
I ran
/sbin/zramctl
Step 1. The system has been running for a few days without a restart.
I have lots of browser tabs open and other apps running in the background (DejaDup).
It shows a 2.9:1 ratio of ZRAM compression (Data 1.7G / Compression 587M). The compression ratio is close to the range of 2:1.
NAME ALGORITHM DISKSIZE DATA COMPR TOTAL STREAMS MOUNTPOINT
/dev/zram0 lzo-rle 3.6G 1.7G 587M 614.7M 2 [SWAP]
Step 2. After a restart
Data 4K / Compression 80B
I’ll watch it from time to time and close the browser tabs when finished working.
I withheld creating a bug report.
