Hi!
I have a question about zram + swapcached. I know that zram is a
compressed swap in memory, but linux use it's own internal SwapCached
area to store recent swap pages _also_ in memory. I have a 512mb laptop
with a ~128mb zram swap drive.
So zram_stats says:
orig_data_size: 97419264
compr_data_size: 40315919
and: grep SwapCache /proc/meminfo
SwapCached: 90200 kB
So does it mean i have these swap pages in ram twice? First
is compressed, and second is uncompressed by linux internal swapcache
feature?
If it is true, it's not very useful to save ~57MB while it's also in
ram with ~90MB.
Anyway: can i disable linux's swapcache feature at all when i'm
swapping to zram? Or can I limit the maximum swapcached area?
