zram, anyone have an opinion on this?

Although I am surprised at how much infrastructure you have uncovered that is applicable to zram,
this may be more due to my absence of experience with any form of swap.

In this instance, I think we are at least missing a driver called zram, and/or perhaps a clue like zram.ko
indicating some source material.
Also, I can't see any evidence on /etc/fstab that speaks to swapping of any kind.

I expect we may have to wait for 7.0.1 for the rest of the material to appear.
I'd be pleased to have you show otherwise.

Hello Utu,
thanks for your words but my experience comes from the fact that I like to understand how to improve system performance by using hardware and software available without having to invest any more money...
I like to fully understand how things work...

Anyway in your case if you have multiple cores (2 cpus), then using a single zram can be a bottleneck, so you need zram0 e zram1 (it's present in your /dev/ ??)

modprobe zram  num_devices=2   #On July 20th 2011, the zram driver in the linux 3.1 staging area was modified to use zram_num_devices as modprobe parameter
echo $((512*1024*1204)) > /sys/block/zram0/disksize   #Allocate 512MB to zram0
echo $((512*1024*1204)) > /sys/block/zram1/disksize   #Allocate 512MB to zram1
mkswap /dev/zram0
mkswap /dev/zram1
swapon -p 100 /dev/zram0
swapon -p 100 /dev/zram1

But beware, I have not tested anything right now, I just created a swap in ram. Now we need to see if it actually works. It 's likely to miss the module zram.ko as you have highlighted. I'm waiting 7.0.1 too.

Regards.
