13 Optimizations

Note added 2002. Computers have gotten a lot faster, so most of the optimizations discussed below will not be necessary on new machines. I am leaving this stuff in the manual for people who want to write thick books, where some of it still might be useful.

Implementing the principle of least surprises, the default settings of RefTeX ensure a safe ride for beginners and casual users. However, when using RefTeX for a large project and/or on a small computer, there are ways to improve speed or memory usage.

As a summary, here are the settings I recommend for heavy use of RefTeX with large documents:

     (setq reftex-enable-partial-scans t
           reftex-save-parse-info t
           reftex-use-multiple-selection-buffers t)
