On my machine, which is a default desktop I have the following: $ swapon -s Filename Type Size Used Priority /dev/sdc3 partition 33436668 0 -1 /dev/zram0 partition 2044092 0 5 /dev/zram1 partition 2044092 0 5 /dev/zram2 partition 2044092 0 5 /dev/zram3 partition 2044092 0 5 /dev/zram4 partition 2044092 0 5 /dev/zram5 partition 2044092 0 5 /dev/zram6 partition 2044092 0 5 /dev/zram7 partition 2044092 0 5
This is with Trusty. Does this mean it's used and enabled by default and therefore this bug can be closed? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/381059 Title: use zram-config by default Status in “linux” package in Ubuntu: Confirmed Status in “ubiquity” package in Ubuntu: Confirmed Status in “zram-config” package in Ubuntu: Invalid Status in “linux” source package in Raring: Confirmed Status in “ubiquity” source package in Raring: Confirmed Status in “zram-config” source package in Raring: Invalid Bug description: There is already zram-config in Ubuntu, a package to enable compressed RAM swap: https://launchpad.net/ubuntu/+source/zram-config Starting with kernel 3.8 zram (a rewrite of older compcache) is out of staging. Please enable it by default. See also: http://www.webupd8.org//2011/10/increased-performance-in-linux-with.html https://launchpad.net/~shnatsel/+archive/zram === Original description === Including compcache by default can have a number of benefits for the average, and not so average, Ubuntu user. For the average user, compcache will decrease disk swapping, which will increase perceived performance and decrease hits, which for laptop users will improve battery life. Since many users use laptops and netbooks these days, this is a big audience and would make many people happy. Desktop users will also benefit, as their disks will be less active and their electric bills may go down a tiny bit. For the not-so-average user, such as those that run virtualization, they can run more VMs. With Ubuntu striving to be bigger in the server space, this could be a big deal. For me, I (unfortunately) run Windows in KVM, and it appears that enabling compcache improves my VM's performance. Embedded devices and netbooks (such as those that run Ubuntu Netbook Remix) will benefit, as they have little RAM, and since compcache sort of increases RAM, it will make these devices more capable. Since compcache is already in the Ubuntu kernel (see bug 200765), the only thing left is to either add an initramfs script or a udev script (IMHO, the udev approach is cleaner) as described here: https://wiki.ubuntu.com/Compcache compcache: http://code.google.com/p/compcache/ Thanks!
