Internet Explorer 9 is fast. But if you find that your tabs open slowly, try some of these troubleshooting steps:

First and foremost, check if you have a bad add-on. Run Internet Explorer 9 in No Add-ons mode and see if makes a difference.

If it does, then its probably one of your add-ons creating a problem.

Through Internet Options > Manage Add-ons, you can enable/disable each add-on to identify which, if any, add-on is creating problems.

Do you have a Java Plug-In’s SSV Helper 2 plugin installed? It is know to cause such delays. Disable it and see if it helps.

Do you use Spybot? Or have you added many websites to the Restricted Zone?

Remove all sites added by Spybot’s Immunize:

Open regedit > Navigate to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap

Delete the following sub-folders:
Domains, EscDomains, Ranges

Next, go to this key HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\P3P

Delete the sub-folder History

Do the same for HKEY_LOCAL_MACHINE key.

Also try the following, if you are still perplexed:

From a Command Prompt window, Run the following command:

regsvr32 actxprxy.dll

This re-registers the ActiveX Interface Marshaling Library.

Hope something helps!
