the Zend Studio performance issue

hi guys, if you read the reviews on this page: http://www.php-editors.com/review/?editor=16 , you will notice that a lot of people don't use zend studio for the simple reason that it's lacking in performance... this includes myself. i would really love to use it because of all the features, but when i use the gui, i want the program to respond instantly, which it doesn't do... it's easy to blame java for this, but on the other hand, a program such as azureus ( http://azureus.sourceforge.net ) seems to perform better... to me, performance is the only (yet fatal) reason i don't use zend studio... i kinda get the idea you're missing out on sales because of this issue.. i hope you can somehow resolve this all some day.. ron
