The box works better when using these. Frontcache would improve things further. It will balance the tmem vs physical memory dynamicily making it a better solution than zram. I'd love to see this in the kernel. Thanks Ed Tomlinson PS. At work we use AIX with memory compression. With the workloads we run compression lets the OS act like it has 30% more memory. It works. It would be nice to have a similar facility in Linux.
