This might be of interst as to why it's even slower than OOo.

The OOo event and drawing models are all finely-tuned by Sun's engineers for X11 and Windows, and these models tend not to mesh well with Apple's native Mac OS X event and drawing models, so there's a sometimes-significant penalty there.

 

Text, for instance, is rendered through ATSUI to give all the native font goodness and advanced features (like Mac OS X's best kashida implementation IMO :D ), and X11 doesn't have all the great native features, anti-aliasing, etc., nor does OOo provide the right-sized chunks of text that make ATSUI fastest :-(

 

The other common issue in this area is that Java is somewhat heavy in its memory demands, so if you're running a machine with low memory (768 MB or less, these days), especially with many other apps open, that will cause paging and swapping and seriously degrade performance.
