Which of my Visual Studio extensions are slowing?

Question

My Visual Studio 2012 has become slow to open. In 'safe mode' it's fast again. Presumably some extensions are slowing Visual Studio. Which?

Is there an analogue of Internet Explorer's feature which shows load time for each extensions? http://blogs.msdn.com/b/ie/archive/2009/07/18/how-to-make-ie-open-new-tabs-faster.aspx

Thanks Jesse, ActivityLog.xml has the information I want. Unfortunately, it's unreadable. I wrote a Python script to extract the relevant details

import sys
from bs4 import BeautifulSoup
try:
    f = open(sys.argv[1])
except IndexError:
    f = sys.stdin

soup = BeautifulSoup(f)

loads = dict()

for entry in soup.find_all('entry'):
    description = entry.find('description')
    if not (description and "package load" in description.get_text() ):
        continue

    print(entry)
    print()

I solved my similar problem with "The Activity Log Profiler". It's just an xsl-Stylesheet for the Activity Log and shows the HotSpots and Errors in current ActivityLog.xml
