Today's featured post from the community is by Gonzalo Ruiz from Avanade. He posted a way to improve your async performance in one click.
He writes, "With CRM 4.0 it was often the case that the Asynchronous processing service would start lagging due to the rapid growth of the AsyncOperationBase table in SQL getting to millions of records in just a few months. This was often happening because of the amount of workflows triggered in the system. For example, if you create a workflow that triggers every time an activity is updated, you might end up flooding the database with system job records very quickly. "
