Well, X _does_ add some overhead, but maybe its not the overhead thats
the problem for this application. There could be many other x related
problems too like suboptimal drivers or a suboptimal configuration.
Please not flame, I think everyone is sick of reading x-pros/-xcons mails....

Well, as I said it works quite well for me also using the X11 pipeline
(Netbeans, sun's java ide was quite useable on my Athlon-600 which is
ok in my eyes) - so I expect it to work equal "well" on Solaris.
And if you need highest 2d performance you can on both platforms
switch to OpenGL which does sometimes wonders (and sometimes not ;) ).
The only thing I am completly unhappy with is that the X11 pipeline of
java for now does not use render at all which means tons of getImage
calls and software-loops as soon as you start using alpha-values or
