Additional processing is required to support block folding and the Outline view. This analysis is usually not a performance factor but if a problem is perceived the analysis can be disabled (or re-enabled) via the corresponding check-boxes, as shown below. Also, Code Assist can be considered intrusive by touch-typists, so the facility can be entirely disabled, or if automatic invocation is enabled, the interval to delay can be specified. Quick Fixes can also be enabled or disabled via this panel.
