I use Quarz skin which does not install any additional plugins and was snappier than confluence in the past - but I will try. Also I installed some addins (youtube, etc...) - I will see if something improves, if I remove them.
Also I use profiles - is there something to take care here?

I'll have a look on the other tips!

Thanks, again,
J
