Working with SSRS; we have a report history that's taking 100+ seconds to run (and is timing out, generating the error "System.Web.Services.Protocols.SoapException: System.Web.Services.Protocols.SoapException: An error occurred within the report server database. This may be due to a connection failure, timeout or low disk condition within the database."), yet when we do the query on the server, it's instant. We've looked at the memory configuration and timeout configuration
(Memory: http://msdn.microsoft.com/en-us/library/ms159206(v=sql.90).aspx Timeout: http://stackoverflow.com/questions/840629/reporting-services-report-timeout). Still, the discrepancy exists between the two.
