Rule Name

Querying taking too long: Exchange Search Slow First Batch is over 10.


A full crawl of the database can use a significant amount of resources on a Mailbox server, depending on the size of the mailbox database. During more intensive phases, this use can disrupt mail flow. Because delivery of mail should take precedence over content indexing, a new throttling feature in Exchange Search automatically throttles indexing for a particular mailbox database or set. This reduces disk I/O and CPU utilization.
