Which of my Visual Studio extensions are slowing?

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


You can start Visual Studio from the command line and specify the /log option to have Visual Studio write all details to the ActivityLog.xml. It's not a pretty pop-up dialig, but you can get the information you want from there.

See: http://msdn.microsoft.com/en-us/library/vstudio/ms241272.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
    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() ):


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


There is also a Blog-Entry about it: http://startbigthinksmall.wordpress.com/2011/11/08/activity-log-profiler-find-out-which-extension-is-slowing-down-your-visual-studio/

$this->settings empty in Extbase extension

typo3 extbase

recently I created an extension with the new Extension Builder (TYPO3 6.0, Extbase 6.0). To see if the setup.txt works I added a simple line to it:
