- <title>Code Path Cache</title>
- <p>The code server incorporates a code path cache. The cache
- functionality is disabled by default. To activate it, start
- the emulator with the command line flag <c>-code_path_cache</c>
- or call <c>code:rehash()</c>. When the cache is created (or
- updated), the code server searches for modules in the code path
- directories. This may take some time if the the code path is long.
- After the cache creation, the time for loading modules in a large
- system (one with a large directory structure) is significantly
- reduced compared to having the cache disabled. The code server
- is able to look up the location of a module from the cache in
- constant time instead of having to search through the code path
- directories.</p>
- <p>Application resource files (<c>.app</c> files) are also stored
- in the code path cache. This feature is used by the application
- controller (see
- <seealso marker="application">application(3)</seealso>) to load
- applications efficiently in large systems.</p>
- <p>Note that when the code path cache is created (or updated), any
- relative directory names in the code path are converted to
- absolute.</p>
