What's the difference between OpenJDK and Sun Java for the end user? [closed]

Solution 1:

Suns JDK is much faster for many applications using advanced graphic capabilities (2d and 3d), to the point that some applications are actually not usable using openjdk. See eg:

If I download the .tar.gz version of SweetHome3D (including the Sun JRE 1.6.0_20), the performance is excellent : moving inside the 3D view is smooth and easy to use If I launch it with Java Web Start (the one that comes with icedtea6-plugin package, that launches it under OpenJDK version 6b18-1.8-4ubuntu3), the 3D view is extremely slow, and unuseable.

Solution 2:

There is no difference except for those applications which don't work properly with the OpenJDK.
