Tiffany,
To my knowledge SAP isn't even acknowledging that there is an issue... but I could be wrong, that is just the impression I have gotten. We have submitted several incidents in the past on this, but as of late have just been trying to find ways to workaround the performance (e.g. scheduling) issues.
We tested with Patch 2 (of 4.1 SP4), but did not see any change in our environments. From what we have heard though, some folks did see an improvement... not sure why though. We have compared environments, reports, etc. Still investigating that on our end to see if we can find a difference, but nothing yet.
As an aside, if you are completely unfamiliar with the WebiAdminTool, Matthew Shaw just recently released this awesome wiki on it and I have found it very helpful: http://wiki.scn.sap.com/wiki/display/BOBJ/WebiAdminTool
Thanks,
Missy
