[lubuntu-devel] Spreadsheet for testing RAM for installing. Was: Re: non pae

[Phill. Whiteside]

Hi,

so xenial needs less RAM when installed over trusty? 141MB down to 116MB.
This is somewhat contra to the perceived thoughts of 16.04 needing more
resources than 14.04. It would be  a great statistic to push forward for
those who doubt changes to the new kernel and its underlying system.

Regards,

Phill.
