why generic-pae kernel on Lubuntu?

Asked by LXCC on 2010-10-06

As Summary,
why generic-pae kernel on Lubuntu?

I mean, in http://lubuntu.net/about i read this:
"Please join us and contribute creating a lighter, less resource hungry and more energy-efficient Linux Desktop."
and in http://en.wikipedia.org/wiki/Physical_Address_Extension :
"In computing, Physical Address Extension (PAE) is a feature to allow x86 processors to access a physical address space ... larger than 4 gigabytes."

I think: the key word is "less resource hungry".
So, i think also, the largest percentage of Lubuntu's users, install it on computers with less than 4GB of ram.
For example the olds pentium 4 motherboards cannot have more of 4 GB ram.

Thanks everybody.

I don't think pae kernel will make the computer more ressource hungry. I agree with you, most old computers will not have 4GB of memory, but I don't think using this kernel has any cost on performances / ressource management. And in case someone has the 4GB, then he can make the most of it.

It just means that even if a user installs 32bit on their systm it will still be able to use 12Gb RAM maximum. I believe its just a precaution.
