The Ubuntu kernels also have zswap since Saucy. It may be a simpler option, needing only a change to the kernel command-line ( add zswap.enabled=1 ). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/381059 Title: use zram-config by default To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/381059/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 381059] Re: use zram-config by default
On my machine, which is a default desktop I have the following: $ swapon -s FilenameTypeSizeUsedPriority /dev/sdc3 partition 334366680 -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.

[Bug 381059] Re: use zram-config by default
I'd like to point out that zram is also more secure than swapping to a swap partition on the HDD; since the data never leaves memory, there's no need for cryptswap. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/381059 Title: use zram-config by default To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/381059/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 381059] Re: use zram-config by default
I've got a system with 16gb ram, I still use zram. In the situations I do run low on memory (which happens, I do machine learning) zram will improve performance massivly. And I have yet to see a single benchmark where zram decreases system performance at all. In fact it'd be interesting to see numbers of a performance test using say 95% of the available memory with and without zram. Although I recon that would be a scenario that would be fairly rare. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/381059 Title: use zram-config by default To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/381059/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 381059] Re: use zram-config by default
zram-config is in main since it exists, all thats needed is to seed it generally in the ship seed and to have some detection code in ubiquity that installs it by default in setups where it makes sense to have it (low ram) ** Also affects: ubiquity (Ubuntu) Importance: Undecided Status: New ** Changed in: zram-config (Ubuntu) Status: New = Invalid ** Changed in: ubiquity (Ubuntu) Status: New = Confirmed ** Changed in: ubiquity (Ubuntu) Importance: Undecided = Wishlist ** Also affects: ubiquity (Ubuntu Raring) Importance: Wishlist Status: Confirmed ** Also affects: linux (Ubuntu Raring) Importance: Undecided Status: Confirmed ** Also affects: zram-config (Ubuntu Raring) Importance: Undecided Status: Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/381059 Title: use zram-config by default To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/381059/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 381059] Re: use zram-config by default
I believe zram-config can be shipped unconditionally. It will decrease performance on a hypothetical machine with a slow CPU (or low memory bandwidth) and a really fast storage, but I couldn't find any such devices on the consumer market. An Intel paper suggests that zramswap-like setups are beneficial even for ARM boards, which have slow CPUs and low memory bandwidth: http://www.celinux.org/elc08_presentations/belyakov_elc2008_compressed_swap_final_ppt.pdf -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/381059 Title: use zram-config by default To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/381059/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 381059] Re: use zram-config by default
Oh, and as for Ubiquity, I've received reports that it enables zramswap on the installed system if no other swap is available to it.

Also note that kernel 3.8 will ship a faster lzo module, used by zram for compressing/decompressing RAM.
