For anyone having that delay issue on IE8 startup, try these steps...it worked like a charm for me.
1. Open regedit
2. Go to this key: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap
3. Delete the following sub-folders: Domains, EscDomains, Ranges
4. Go to this key: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\P3P
5. Delete the sub-folder History
6. Repeat steps 2-5, but in HKLM.
