User Comments:
GUEST: opening a css file.

GUEST: Moving files around

GUEST: It happens all the time, when I run NetBeans and try to open any document

facilityderek: Opening a large css file that contains "errors" ( nonstandard tricks for MSIE brower compatibility )

GUEST: I dragged a css file into netbeans and it got delayed. Before dragging I was working with php files. There were more than 20 php files open in netbeans.

Comment 2 Marek Fukala 2010-04-27 15:48:48 UTC

There are two kinds of problem in the snapshots:

1) there is a heavy classloading triggered from the CssPreviewTopComponent initialization

2) EmbeddedBrowserFactory.getDefault() called in the class constructor takes a lot of time 
 
I've deferred the SAXParser initialization done in the constructor (which could possibly trigger the heavy classloading) to later times: web-main#7d1e541e371c

Now what can possibly cause #1 is loading of the EmbeddedBrowser classes, the problem #2 is caused by the embedded browser, reassigning there
