Salutations, I've had excessive swapping (high cpu usage with kswapd) and the termination of running programs (like Skype) due to zram swapping. I used zramswap from the AUR to start the service, but it only calls on the kernel to produce the block devices. A compressed zram device (like maybe F2FS partition zram block) for /tmp should eliminate the risk of /tmp files taking precedence over running programs with a zramswap. It would limit /tmp performance to the max decompression speed of the zram block. Regards, Mark On Thu, Mar 13, 2014 at 8:06 AM, Simon Perry <arch@sanxion.net> wrote:

How much RAM do you have?
zram is probably solving a problem you don't have.
Enable it on a VPS that has 256MB RAM (which is supposed to be its use case) and get back to me.
