Its good iddea add swap in SSD?

[kdemeoz]

... I personally recommend you to just install the package zram-config just in case so that if you exceed RAM usage it will at least have something to swap to

This fascinated me; i did not know of this package. I've now researched it, then tested it in my 2 Maui VMs, to help me decide if i will take the plunge to actually install it into my real Mauis in Lappy & Tower [& maybe also then use gparted & fstab to remove my existing Swap partitions]. The VM results seem remarkable:

System [VB VM]
Base Memory 4096
Processor(s) 2

   
   

Code:

kdemeoz@Maui-VM:~$ cat /proc/swaps
Filename                                Type            Size    Used    Priority
/dev/sda2                               partition       2097148 0       -1
/dev/zram0                              partition       1011520 0       5
/dev/zram1                              partition       1011520 0       5

All that looks great, but i have one question: does zram in any way conflict with / steal memory from tmpfs [in which as you can see i run /tmp; pls note -- all the following is from my VM, but i do use a similar arrangement in my real Mauis]:

Code:

kdemeoz@Maui-VM:~$ df -h
Filesystem       Size  Used Avail Use% Mounted on
udev             2.0G     0  2.0G   0% /dev
