Comment 25 for bug 776999

Andrew, Ubuntu 11.04 32-bit automatically installs the PAE extension so you will be to use up to 64 GB memory. I am running 16GB RAM and tested it, see further information here http://ubuntuforums.org/showpost.php?p=11004403&postcount=7. Also the 32-bit Ubuntu 11.04 solved the issues with NVidia GPU, external monitors are working very well too.
On one hand, I have a subjective impression that the 32-bit system is slightly slower than 64-bit one but on the other hand, even the 32-bit Ubuntu 11.04 is far away faster then MS Windows 7 Enterprise 64-bit, again, my subjective opinion, feeling and some objective test I performed (I recall, my "fastest laptop in the world" has i7-2820QM, 16GB RAM, SSD Vertex3 Pro 240 GB with 6.0 GB/s speed)
- MS Window 7 64-bit takes 2.2 GB Memory after the start, running nothing else, Ubuntu ~ 400MB after the start.
- Ubuntu reacts faster and smoother then MS Windows 7 etc...
Never then less, Ubuntu team, wake up and fix the 64-bit version!
