Flash Builder mxml editing painfully slow

Jun 25, 2009 4:35 PM

I'm running Flash Builder on a Windows Vista machine.  I created a default application project and created a new component.  I started editing that new component in the MXML editor, opened the help window to look up some stuff, when back to edit and it freezes up for about 10 seconds.  I edited a little more and then it freezes up again for 10 seconds.  I looked at the FB process footprint (gumbo.exe) and its 500Megs, 5 times larger than anything else including Photoshop. I was also running Flex Builder 3 at the same time.  Is there some known issues...googling I found a similar complaint for Mac.

    Try turning off LiveDocs (it's in the top of the Flash Builder preferences page). We've found a bug in Java with http requests not timing out when they should. It's fixed in JRE 1.6 so this only repros with JRE 1.5.


    Hope that helps!
