Subject Re: Sharepoint Job - Incremental Crawling

Got it.
Is there any way we can increase the speed of the minimal crawl. Currently
we are running one VM for manifold with 8 cores and 32 gb Ram. Postgres
runs on another machine with a similar configuration. Have tuned the
Postgres and Manifoldcf parameters as per the recommendations. We run a
full vacuum once daily.

Would switching to a multi process configuration with manifoldcf running on
two servers give a boost.
