ImageIO isn't faster than TextureIO as far as I know. StackOverflow isn't a good source of information about JOGL. People can vote but more votes don't mean that what they write is true. A misuse of TextureIO can cause slowdowns. Please don't be so peremptory when quoting StackOverflow in the future and this answer is better on my view:

Moreover, you quote a comment written in 2010 at the time of JOGL 1, LOL. We didn't use our own PNG loader at this time. TextureIO in JOGL 1 is closer from AWTTextureIO in JOGL 2, not TextureIO in JOGL 2.
