I was thinking of replacing Mint on my desktop with Lubuntu, mainly because all else being equal, I prefer efficient software and Lubuntu is advertised as being super-efficient.
However, on a simple test I found that it isn't even as memory-efficient as Mint? I booted my machine from the Lubuntu USB and ran 'top' in a Terminal window. It consumed slightly more than 1GB of RAM -- more than I expected, so I removed the USB and rebooted with native Mint from my hard drive. Mint takes only 740MB. Even with Firefox up playing a flash video, Mint is still well under 1GB memory.
What gives? I thought Lubuntu was supposed to be super-efficient. Is this not a fair test? Should it be USB vs. USB?
Just curious -- thanks for reading!
