Recommended configuration for crawling large hosts When defining content sources to crawl in SharePoint Search, the maximum number of threads that can simultaneously make requests to a host is set to 12 by default OOB. This value affects the rate of content discovery from the host. For all small and medium sized hosts (<10M), this thread count is sufficient. But if the target host is >10M, we recommend you increase the thread count. Workaround For large hosts (>10M items), we recommend you set the number of threads to 32 or more. This is over-and-above the recommendation to have dedicated crawl targets that helps manage load on front ends efficiently without impacting performance observed by users of that host.
