Re: [orca-list] Processor or memory: which matters most with screen readers?

[Didier Spaier <didier slint fr>]

As a side note, using swap in zram can increase the practically
usable RAM. For instance here:
root[/home/didier]# swapon
NAME       TYPE       SIZE USED  PRIO
/swapfile  file      1024M   0B    10
/dev/zram1 partition 13,8G   0B 32567

root[/home/didier]# LANG=C free -th
              total        used        free      shared  buff/cache 
available
Mem:          7.7Gi       579Mi       6.3Gi       128Mi       800Mi 
 6.7Gi
Swap:          14Gi          0B        14Gi
Total:         22Gi       579Mi        21Gi

Don't take as granted that I can have 21G of usable RAM with 8G
of physical RAM though as I just rebooted and the zram is empty.
As the swap device in zram is sized to 1.5 times the size of the
physical RAM and assuming a  compression factor of around two,
if I fill the swap in zram I will end up with (1.5+0.25)*8G
or 14G for 8G installed, which is good enough. The price to pay
is some CPU usage for compressing/decompressing, practically
unnoticeable here.

Best, Didier
