Internet Explorer 8 has much worse performance than Internet Explorer 7 on Windows 7 for Reporting Services reports
I provide SSRS 2008 reports to my client using Windows Authentication on a remotely hosted server. They recently upgraded everyone to Windows 7 and Internet Explorer 8, and now the performance is so bad they can't use these reports. It takes close
to a minute for a report to load. Subsequent report loads are somewhat faster but still painfully slow.
When I roll back IE 8 to IE 7 on their test machine, the performance is fine, but the client's IS manager will not roll back everyone to IE 7; nor will he install Chrome or Firefox. I upgraded the server from SSRS 2008 to SSRS 2008 R2, but that did
not help. I've changed all of the IE 8 options I can think of, without any luck. I will surely loose this client if I can't resolve this issue, so any help would be appreciated.Scott D Duncan

Hi Scott,
Could you look into and compare their TimeDataRetrieval,TimeProcessing,TimeRendering,Source in the ExecutionLog2/ExecutionLog3 view against report server database between IE7 and IE8. See
http://blogs.msdn.com/b/robertbruckner/archive/2009/01/05/executionlog2-view.aspx on Analyzing and Optimizing Reports. Then, we can futher analysis their performace issue. Additionally, to improve report performance, you can enable report
cache. See http://msdn.microsoft.com/en-us/library/ms155927.aspx on Caching Reports.
thanks,

Jerry, thank you for the info on viewing the execution logs.
Preliminary testing is showing that cached vs. uncached for these reports is about twice as fast, so I should definitely work on setting up a nightly schedule to cache them (today's date is a parameter).
I am still running tests, but the preliminary results are that the Vista / IE 8 and Win 7 / IE 7 are about 50% faster than the Win 7 / IE 8 combo. Not sure why this is happening. Are there any IE 8 or Win 7 settings that might be causing
this?Scott D Duncan
