Problem: High CPU consumption (slow queries)

CPU consumption is high and content-based retrieval (CBR) query times are slow.

Table 1. Possible causes of slow queries when CPU consumption is high
Possible cause	Troubleshooting strategy
Servers are configured in IndexAndSearch mode	Use multiple servers. For more information, see Query optimization: Multiple search servers.
The index server and the search server are collocated on the same machine or physical server	Do not collocate servers. For more information, see Query optimization: Multiple search servers.
Insufficient cache memory	For file system caching, allocate at least 4 GB of memory. If possible, allocate 8 GB.
Database-first search that yields many hits in the database search	Optimize CBR query performance: Search full-text before database.
