Using a standard people picker on a task form - searching the AD (active directory) is very slow.
- John Smith (email@example.com)
When I enter smith in the people picker and hit CTRL+K or the little checkmark, the user is resolved right away as "John Smith".
Now when I use the addressbook feature and search for "smith", it takes about a minute for it to find "John Smith".
The AD contains about 2000 users so size is not the issue. How can I analyze this issue and speed up the search?
