Microsoft distributes Microsoft SQL Server 2008 R2 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 R2 fix release.
Consider the following scenario in Microsoft SQL Server 2008 R2 Reporting Services (SSRS 2008 R2):
You have a report that contain one or more parameters. The parameters contains many selectable values. For example, the parameters contain more than 1000 selectable values.
The report is displayed by using one of the following ways:
The URL of the Report Server Web Service
The ReportViewer 2010 Web Forms control
The SharePoint ReportViewer 2008 R2 web part for SharePoint 2010
You try to view the report in Internet Explorer.
In this scenario, the report takes a long time to load. Additionally, Internet Explorer may experience high CPU usage when the report is loaded.
Note The issue does not occur when you view the report by using a third-party web browser.
This issue occurs because of a known issue in Internet Explorer. Specifically, the Async postbacks that are made by an UpdatePanel control are slow to load. For more information, click the following article number to view the article in the Microsoft Knowledge Base:
