server to store the data in.
- Mailparse. Efficient parsing of email requires this extension.
Submission by email or SMS-over-email uses this extension.
- Sphinx Search. A client for the sphinx server, an alternative
to MySQL or Postgresql fulltext search. You will also need a
Sphinx server to serve the search queries.
You will almost definitely get 2-3 times better performance from your
site if you install a PHP bytecode cache/accelerator. Some well-known
examples are: eaccelerator, Turck mmcache, xcache, apc. Zend Optimizer

Sphinx
------
To use a Sphinx server to search users and notices, you also need
to install, compile and enable the sphinx pecl extension for php on the
client side, which itself depends on the sphinx development files.
"pecl install sphinx" should take care of that. Add "extension=sphinx.so"
to your php.ini and reload apache to enable it.
You can update your MySQL or Postgresql databases to drop their fulltext
search indexes, since they're now provided by sphinx.
On the sphinx server side, a script reads the main database and build
the keyword index. A cron job reads the database and keeps the sphinx
indexes up to date.
