-This directory contains data files in the format of PHP's serialize() function.
-The source data are typically array literals in PHP source files. We have
-observed that unserialize(file_get_contents(...)) is faster than executing such
-a file from an oparray cache like APC, and very much faster than loading it by
-parsing the source file without such a cache. It should also be faster than
-loading the data across the network with memcached, as long as you are careful
-to put your MediaWiki root directory on a local hard drive rather than on NFS.
-This is a good idea for performance in any case.
-
-To generate all data files:
-
- cd /path/to/wiki/serialized
- make
-
-This requires GNU Make. At present, the only serialized data file which is
-strictly required is Utf8Case.ser. This contains UTF-8 case conversion tables,
-which have essentially never changed since MediaWiki was invented.
-
-The Messages*.ser files are localisation files, containing user interface text
-and various other data related to language-specific behaviour. Because they
-are merged with the fallback language (usually English) before caching, they
-are all quite large, about 140 KB each at the time of writing. If you generate
-all of them, they take up about 20 MB. Hence, I don't expect we will include
-all of them in the release tarballs. However, to obtain optimum performance,
-YOU SHOULD GENERATE ALL THE LOCALISATION FILES THAT YOU WILL BE USING ON YOUR
-WIKIS.
-
-You can generate individual files by typing a command such as:
- cd /path/to/wiki/serialized
- make MessagesAr.ser
-
-If you change a Messages*.php source file, you must recompile any serialized
-data files which are present. If you change MessagesEn.php, this will
-invalidate *all* Messages*.ser files.
-
-I think we should distribute a few Messages*.ser files in the release tarballs,
-specifically the ones created by "make dist".
