Hi Steve,

In my experience a limit at 512 MB is too low anyhow.

If a limit needs to be fixed it should be at least 10024 MB and not less. About 
pre allocation : instead of giving the zram devices 50% of the total amount RAM 
provided by the hardware, 25% would be a good number, which is what the 
developer of the compcache project advised.
Here is the wiki,

here are benchmarks,

here on eeepc with Ubuntu, back in 2011:
http://code.google.com/p/compcache/wiki/Eeepc701

(Ubuntu was using 25% of the available ram for the zram module).

I have put test versions of Ubuntu Precise remixes with compache enabled
and not limited in them. I have installed the bigger (a version setup
fully up to date, with Openbox and a panel of applications) to a T30 IBM
Thinkpad having 512 MB RAM. The only annoyance I met with have been the
kernel swapping while less than half of the physical memory was yet
used, which I fixed by configuring swappiness in the sysctl.conf file
(for this annoyance I don't know what should be done : seek for bug
reports at kernel.org maybe ?)

Could this bug report be reopened, and a request to raise the limit RAM
considered ?

Thanks,
Mélodie
