TagSleepInterval
The value in this registry entry sets the length of time in milliseconds that the auto-tagging feature sleeps between the processing of items, between the processing of folders in the crawl mode, and between the processing of folders in the search mode. The default value is 1.
Try increasing the sleep interval so the crawl doesn't happen so often, and increasing the TagMinItemsforCrawl.
The best thing that you can do is keep the number of emails in the folder down below 1,000 emails. Train users that they don't need to keep 10,000 emails in their in-box anymore, they can track them in CRM. |
