Symptoms

How can we crawl more often?

There are several aspects to crawl performance and the impact or load a crawl places on the system.

 

Changes

The indexer is a java process that runs different threads to get the crawling job done.  As any java process it is impacted by the amount of resource it has access to.  When the crawler is updating content is it doing it a document at a time and the demand on memory is not high.  But when it is indexing and classifying more information is held in memory and memory can impact performance.  In addition secondary processes or workclients can be added to speed up the content update thru indexing steps by distributing the load of crawling.  If the system resources are not available to the crawler then the time to crawl will be slower.
