Written by Michael Larabel in Operating Systems on 28 February 2012. Page 3 of 3. 48 Comments

The performance advantage of 64-bit over 32-bit Ubuntu is clear. If you are still running the 32-bit version on 64-bit capable hardware you should really consider switching with the "Precise Pangolin" now that the 64-bit Flash is on par with the 32-bit version, OpenJDK works well on 64-bit, etc. The 32-bit situation should at least become a bit more interesting with Linux x32 support.
