FIX: The performance decreases when you open the Report Builder (RB) ClickOnce application after you install SQL Server 2008 Service Pack 1

This article has been archived. It is offered "as is" and will no longer be updated.
Microsoft distributes Microsoft SQL Server 2008 fixes as one downloadable file. Because the fixes are cumulative, each new release contains all the hotfixes and all the security fixes that were included with the previous SQL Server 2008 fix release.
Symptoms
Consider the following scenario:
  • On a computer that is running Microsoft SQL Server 2008 Reporting Services, you install SQL Server 2008 Service Pack 1 (SP1).
  • After the installation is complete, you open the Report Builder (RB) ClickOnce application.
  • You use the RB ClickOnce application to download the installation files.
In this scenario, you notice that the download speed is much slower than it was before you installed SQL Server 2008 SP1.
Cause
This issue occurs because more than 1,000 additional files are added to the /ReportBuilder server installation folder after you install SQL Server 2008 SP1. The additional files that are added to the /ReportBuilder server installation folder cause the download speed to decrease.
Resolution
The fix for this issue was first released in Cumulative Update 4 for SQL Server 2008 Service Pack 1. For more information about this cumulative update package, click the following article number to view the article in the Microsoft Knowledge Base:
973602 Cumulative update package 4 for SQL Server 2008 Service Pack 1
Note Because the builds are cumulative, each new fix release contains all the hotfixes and all the security fixes that were included with the previous SQL Server 2008 fix release. Microsoft recommends that you consider applying the most recent fix release that contains this hotfix.

Microsoft SQL Server 2008 hotfixes are created for specific SQL Server service packs. You must apply a SQL Server 2008 Service Pack 1 hotfix to an installation of SQL Server 2008 Service Pack 1. By default, any hotfix that is provided in a SQL Server service pack is included in the next SQL Server service pack.
Status
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
