Developer panel for SharePoint 2010

(This series is about the development of the content)

Performance is one of the big challenges that we are likely to face when developing SharePoint 2007 applications. The last thing we want to see is that when a user refreshes a page, it takes several seconds (or more) to see the page slowly open. If you really have a performance problem, the first thing you need to know before performing performance tuning is "where is the system performance bottleneck?" "In other words, if you can't find out why the system is running slowly, then performance optimization is not going to work."

There are many tools to find system bottlenecks, from performance monitors built into Windows Server to SQL profiles, CLR profile, and so on, as useful tools. And for a SharePoint page, it seems that there is no special use of bad tools, can quickly and clearly tell developers, the page on the various parts of the performance, will create what kind of impression, are occupied by how long the running cycle.

The developer panel (Developer Dashboard) is a new feature in SharePoint 2010. It is an information panel located at the bottom of the page that shows you how long each component on the current page is running, what database calls the current page is running, how much time each database call takes, and so on. If a page is found to run slowly, developers can quickly find the culprit that causes the page to slow down as a snail through the developer panel.

The following is the developer panel for the default home page of the SharePoint 2010 Workgroup Web site:

This includes the execution time of the controls on the page:

Some useful information about the current Web request:

Calls to all databases that are raised by the current page, and their execution time:
