Strange performance issue in SSRS SharePoint integrated / Kerberos


hi,

current setup / situation:

four server farm bi portal:

  • sql server instances
  • ssas instances
  • sharepoint apps (ssrs, central admin ...)
  • sharepoint frontend

three different environments (dev, test, prod) same configuration (servers, versions, cpu/ram,...)

kerberos configured (as far can see) pushing current user credentials forward sharepoint frontend ssrs integrated service app ssas olap cube.

problem:

when connect report on dev dev cube, report execution time 7 seconds. in execution log can see in additional info field, have connectionopentime of couple of milliseconds (~ 20-40).

when connect report on test test cube or dev cube or dev report test cube, have runtimes of 60 seconds connectionopentime of little bit more 2000 ms.

when change data source connection fixed windows account, runtime drops down 7 seconds. when switch "use current user credentials" runtime stays @ 7 seconds 1-2 hours, in drops 60 seconds.

question:

what can cause huge connectionopentime? ad/dns related? claims windows token service? other caching/os issue?

thanks input.
