# Performance Overview

IDOL Server performance generally refers to the performance of the following IDOL Content component operations:

- Index Data. Documents in IDX or XML file format are added to the IDOL Content component.

- Query IDOL server. Users send natural language, keyword or Boolean queries to the IDOL Content component, which analyzes the concept of the query and returns documents that are conceptually similar.

To optimize IDOL Server performance, you must consider the relationship between these operations. The appropriate setup for your system depends on whether your priority is achieving fast query speeds or making new information available to users as quickly as possible.
