I am seeing a large amount of processing time for the Calendar control in SSRS to be returned. We have 2 date fields in the Report Viewer and they each execute at the same time, but take around 6s to come back (this is consistent on multiple servers).

Long Calendar Response Times

This isn't as drastic on the ReportViewer control on the default SSRS Manager that is built into the SSRS Server, but it still is about a 2s delay for that one as well. This is a significant delay to our application and this happens on each and every Page Update. With this being a multi-drilldown table... those post backs happen often, so this is quite annoying.

Our environment is as follows:


  • IIS AppPool: 4.0

<httpHandlers> <add path="Reserved.ReportViewerWebControl.axd" verb="*" type="Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=, Culture=neutral, PublicKeyToken=89845dcd8080cc91" validate="false" /> </httpHandlers> <compilation debug="true" targetFramework="4.0"> <assemblies> <add assembly="Microsoft.ReportViewer.WebForms, Version=, Culture=neutral, PublicKeyToken=89845DCD8080CC91" /> <add assembly="Microsoft.ReportViewer.Common, Version=, Culture=neutral, PublicKeyToken=89845DCD8080CC91" /> <add assembly="Microsoft.Build.Framework, Version=, Culture=neutral, PublicKeyToken=B03F5F7F11D50A3A" /> </assemblies> <buildProviders>

Any Ideas?
