Profiling SharePoint 2010 in v6.0 - 6.3

Date: 24/06/2011
Product: ANTS Performance Profiler

ANTS Performance Profiler versions 6.3 and earlier were not designed to support SharePoint 2010 profiling, but the following workaround may let you profile managed code running on a SharePoint 2010 server with IIS 7 in ANTS Performance Profiler version 6.0 and above.

SharePoint 2010 profiling is supported in ANTS Performance Profiler version 7.0.

To profile SharePoint 2010 with IIS 7 in ANTS Performance Profiler 6.0 to 6.3:

Open the IIS applicationHost configuration file.
By default, this is located in C:\Windows\system32\inetsrv\config\applicationHost.config
In the <globalModules> element, comment out the following line:
<add name="SharePoint14Module" image="C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\isapi\owssvr.dll" preCondition="appPoolName=SharePoint Central Administration v4;SharePoint - 80" />
Immediately below this line, add the following line:
<add name="SharePoint14Module" image="C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\isapi\owssvr.dll" preCondition="appPoolName=RGTestAppPool;SharePoint - 80" />

This sets a precondition allowing ANTS Performance Profiler to load the SharePoint server DLL. ANTS Performance Profiler will now be able to profile code on the SharePoint server.
Follow the instructions on Profiling SharePoint.
