I'm using it here to deploy a lab consisting of about 20 computers
running Ubuntu/quantal and about 100 students.

FAI itself is very reliable, but it is a bit of an effort to set it up
if you are not used to PXE setups etc.

There are many ways to contribute to Ubuntu, described on the Ubuntu

Possible inclusion of zram-config on default install

2012-12-07 Thread Fabio Pedretti 
It would be nice if Ubuntu could include zram-config by default. This package 
set up compressed RAM swap space and can lower RAM requirements for running and 
installing Ubuntu. It should be a win for every configuration. Since kernel 3.8 
the zram module is out of staging, I am using it since precise with no problem.

The bug request is here:
https://bugs.launchpad.net/ubuntu/+source/zram-config/+bug/381059

Re: Possible inclusion of zram-config on default install

2012-12-07 Thread John Moser 
it's a definite win for large configurations infrequent swapping, much 
more additional RAM), as well as for small configurations where there's 
a lot of swapping (faster than swapping).


I wrote and use an init script that breaks up the zswap into n devices, 
1 per cpu execution thread, to fully parallel the operation.  If you 
swap 64KiB at once with 8 core plus hyperthreading, the kernel will do 
16 4k pages in parallel under that configuration--big, multi-CPU, 
hypethreaded servers (it's a big 30% gain with parallel like threads, 
i.e. compression) benefit much from this.


Less useful in VMs, where such things should really happen at the 
hypervisor.

-1. I am not on a netbook and even my laptop have 12gb of Ram.  It
would be nice if Ubuntu did detect your ram and decide but not force
it on people like me who aren't memory constrained.

In an abundant memory situation, the device is set up and sits idle 
consuming zero CPU resources and a few pages of RAM.  As memory is not 
constrained, the few pages of RAM are negligible.  Extremely.

Where necessaries, we already ship and include zram.

E.g. ubuntu nexus7 and ac100 images.

What other images do you want this for? I am not convinced it makes
much sense on i386/amd64.

Dmitrijs.
