Extension:Foxway/How it can make MediaWiki faster

How it should work in my understanding. Do not take these examples literally, they show only the principle.

These primitive examples show that a "slow" foxway can make MediaWiki faster, because one can help make efficient use of the cache.

Example 1. There is wiki markup only.
Source of  wiki page :

WELCOME
some text

When saving a page:

 * $title is
 * $pageSource is
 * $parsed['html'] is

When requesting the page:

 * $title is
 * return is

There is no need to cache

Example 2. add php code for foxway
Source of  wiki page :

WELCOME
echo 'Hello!'; some text

When saving a page:

 * $title is
 * $pageSource is
 * $parsed['html'] is
 * $marker is
 * $code is

When requesting the page:

 * $title is
 * $parsed['html'] is
 * $marker is
 * $tmp is
 * return is

Time is spent for foxway: compileTime:     0.00038 secs serialisedTime:  0.00001 secs unserialisedTime: 0.00001 secs runtime:         0.00005 secs

cache usage
There may be used cache and cache may be smart. One can decide whether to caching based on attendance and runtime foxway.

When saving a page:

When requesting the page:

Example 3. Include page
Source of  wiki page: This is MediaWiki version echo CURRENTVERSION;

When saving a page:

 * $title is
 * $pageSource is
 * $parsed['html'] is
 * $marker is  and
 * $code is  and

When requesting the page:
 * $title is
 * $parsed['html'] is
 * $marker is  and
 * $tmp is  and
 * return is

About cache useage
Actually cache can be much smarter. In addition, scripts can be able to give hints to the cache manager or manage the cache.
 * If in the included page there are not scripts, then just return parsed data for all.
 * If in the included page there are parameters, need save and return data in the context of the used parameters for all.
 * If in the included page there are scripts, you can check: are there global or static variables or any dynamic data?

All this can help make efficient use of the cache.
