I recently had an issue on both Vista x64 SP1 and Windows 7 Beta with IE opening tabs very slowly.
This was following an update to Java to 6.0 update 10 (or 6.0 update 11) where whenever I opened a tab or Window or popup or anything in IE, the following command would run:
This would use up 100% of one of my cores and the tab/window would not complete loading until it had finished, which sometimes took 10 seconds or so.
I figured out that it was to do with the next generation browser plug-in which launches the java applet as a separate process instead of within the browser process. Sun have included this new plug-in since Java 6 update 10 which would explain the issue.
This proved to be highly irritating, so I set about finding a fix and noticed that there were 2 BHO add-ons registered in IE with ‘ssv’ in the name:
Java(tm) Plug-In 2 SSV Helper
Java(tm) Plug-In SSV Helper
So I figured I would disable them to see if it impacts functionality.
The upshot is that it doesn’t impact functionality at all, the 2nd generation plug-in works just fine without those BHO’s enabled. :)
By the way, I recommend process explorer for troubleshooting these painful hanging issues. It is part of the excellent Sysinternals tools and is written by an expert in the Windows Kernel, Mark Russinovich.
