Nella giornata di ieri è stato rilasciato un'aggiornamento che va a migliorare le performance di MOSS.

Di seguito le note salienti:

Issues that the update fixes

•	Workflows run on e-mail-enabled lists by running as the user who designed or deployed the workflow instead of as the user who modified or created the parent item. Note This issue applies to e-mail-enabled items only.
•	Workflows that have versioned conditions do not work correctly after the workflows are deployed by a site template (.stp).
•	Workflows that contain Delay activities are not returned consistently after the set amount of delay time passes.
•	When users are authenticated anonymously, they cannot use a backup domain controller (BDC). This update enables the BDC to explicitly let anonymously authenticated users access the BDC.
•	A BDC consumes a Line of Business (LOB) Web service, and the LOB Web service returns large data sets. When this occurs, the HTTP connection times out. This update lets you configure the time-out value by using the object model.

Improvements that the update provides

•	When you detach and then reattach a content database or when you restore a content database by using the STSADM -o command, a full crawl is not always required. Note Only post-update farms and content databases that are backed up or detached from an updated farm are affected by this improvement.
•	Improvements to scalability and performance are included to support incremental search crawls.
•	Improvements are made to the time that is required to update and to upgrade Microsoft Windows SharePoint Services sites. Note Only post-update farms are affected by this improvement.
•	Improvements are made in stability when you upgrade a farm that has many host header-based named site collections.
•	Support is included for Kerberos authentication to access Shared Services Provider (SSP) Web services in a server farm.
•	Performance improvements are made to the MySiteCleanupJob function in a multi-SSP farm.
•	Search crawl speed is improved.
•	After you apply the update, Microsoft Office 2003 files or 2007 Microsoft Office files that are embedded in a 2007 Office document are searchable.
