modx96 Performance vs. other cms

Hello to the community of one of the nicest os cms. I have installed some cms with modx96 and I am in love with this. I have one problem and that is save after ejavascript:void(0);dit and changes speed working on Linux Browsers and Firefox.
Second is performance in site building on linux webserver. I did not install speedometer but i have done a simple perfomance check. I did the same css and the same site structure to a Joomla Installation and and a modx96.
If i call the sites at the same websapce and server -the joomla web is faster in site building up after call url in browsers. The same test i did with wp and Postnuke. So I am very sorry, but the the difference to modx is big.
Maybe I did a main important installation error or have forgotten something important. For me it would be very helpfull to get the most fastest settings at a very fast server.
If any body could help me I would be very happy, cause modx is for my opinion the momentan best cms and i would like to use for other projekts too.
If needed i can give you an admin account and evry thing is needed to check the performance.
THX for your big development

If you are visiting your site when you are logged in the manager, the quick edit takes few seconds to load. Test the things after logging out of the MODx manager.

Moreover you can use timing tags in the MODx to see the actual timings, see http://modxcms.com/modx-tags.html for "Timing".

THX I installed the tags and found out that the perfomance is fine and the problem a result of Linux local maschine and the internetconnection speed + the Linux Konquerer Javascript settings was.
So i am glad and very happy
