WP-Database-Optimizer helps you to optimize your database by performing some actions for example optimizing tables, deleting revisions and data that can slow that your database. Also 
you can perform backups.
WP Database Optimizer Tools es un plugin el cual ayuda a mejorar el rendimiento de nuestra base de datos, esto es de mucha ayuda cuando sabemos que tenemos muchas visitas y necesitamos aligerar el sitio para un mejor funcionamiento.
Con WP Database Optimizer Tools se puede hacer
<pre><code>Limpiar las revisiones de post
Limpiar los autodraft
Limpiar spam
Limpiar comentarios no aprovados
Limpiar la trash de wordpress
Optimizar las tablas en la base de datos
Reparar las tablas en la base de datos
Se puede hacer un backup de la base de datos ( mas adelante pondra opcion para enviar por email el backup)
</code></pre>

CPU performance testing: 
This plugin does various calculations and string manipulations on your PHP webserver 
and your MySQL database server. To further test the MySQL server, a sequence of MySQL 
inserts, selects, updates and deletes are performed in a separate custom database table 
(we do not use your WordPress tables for this).
Network testing: 
The network is tested by fetching directly from Google’s CDN / apis network. Fetching from the Google 
apis network gives you the nearest server, and will give more accurate results. We also fetch a small 1Mb 
file from our servers as well in case the Google apis is down. The network tests are not yet shown in the 
graphs, we are working on this 🙂
Results: 
After the sequence of tests has finished, the results will be displayed for you to evaluate. MySQL results can 
vary depending on the type of connection your webserver has to the MySQL server. If a “local socket” connection 
is used a typical result for the MySQL query test is 0.05-0.25 seconds. Web hosting providers with dedicated MySQL 
servers will show a slower time/queries per second, as a TCP/IP connection to the MySQL server is made instead of 
a local socket connection.
There are many factors that will determine how fast your website will run. This plugin does not test 
for how many hits/requests per second your provider allows to your website, file system performance is not tested 
either. Use it as a performance test to assess how fast a CPU your provider has allocated to your webserver 
and your MySQL database backend.
Share with your friends, let’s start a competition and see who’s got the fastests servers (hint) 🙂

PHP/MySQL CPU performance statistics

Benchmarks PHP and MySQL and does various performance analysis on these. Especially MySQL analysis is good.

In general benchmarks are short, but quite informative.

Works well and does various important tests

I had to measure the performance of my two local machines (a laptop and a desktop). This plugin came in handy to do exactly that. I only wish that there was a way to export the results for future ref!

Handy

With the performance test plugin you can test the CPU and MySQL speed on your webserver and your MySQL server.
