Track bottlenecks while using Ants Performance Profiler?

This is the difficult part, because
ANTS Performance Profiler does not support SharePoint 2010!
A workaround :

• Open the IIS applicationHost configuration file.  By default, this is located in C:\Windows\system32\inetsrv\config\applicationHost.config
• In the <globalModules> element, find the SharePoint14Module and add in the preCondition value before SharePoint Central Administration the following value: RGTestAppPool;

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.

Why is performance important?

The success of the web performance movement shows that there is increasing interest and value in fast websites. That faster websites lead to more revenue and reduced costs is a well proven fact today. So being exceptionally fast is becoming the dogma for developing (SharePoint) web applications and solutions.

As we want to be exceptionally fast this means that our pages have to load in less than two seconds (based on forrester research) to exceed user expectations. If we want to apply this rule of thumb, we need to ask ourselves:
How can we improve the performance of our SharePoint sites? 

A blog post called “The Importance of Website Performance” by Louis Lazaris contains a very nice summary of very good articles about why web site speed matters:

• Speed Is A Killer – Why Decreasing Page Load Time Can Drastically Increase Conversions

• Page load time – the online business killer

• Google’s Marissa Mayer: Speed wins

I hope this series can assist you while improving the performance of your SharePoint solutions!
