I spent experimenting with JS files in Horde half a day and this is 
what I've found. Generally almost every file that is passed through 
javascript.php is not cached. And this results in a drop of speed, 
especially for such large files as horde.js which is loaded on every 
page.

When horde.js file (with my modifications to not contain PHP code) is 
accessed directly, mnemo task list is loaded in 0.2 second. And when 
through javascript.php - 1.15 second.

Even when I remove PHP specific code from horde.js and pass it through 
javascript.php, I get the same 1.07-1.21 seconds.

Also I tried Michaels solution from CVS a couple of days ago (with two 
.js files one for IE and one for other browsers), and it performed much 
better.

There are couple solutions that came to my mind:
1) Make an exception for horde.js in javascript.php and cache it.
2) Get rid of javascript.php and make all js objects static just like 
you did with css.
4) Don't sacrifice speed for tiny UI bugs. Personally I could live with 
old tooltip implementation.
