Load2Test by DBA InfoPower is a the best for MySQL load testing - they can record actual MySQL production traffic and replay it in staging multiple ways, like "as is", "load parallelization", "think time reduction", etc and generate performance issues root cause analysis on a spot.

I used it with number of my customers and it takes no time to do load testing and get analytics and root cause analysis back (like gathering slow-log data without any impact on a system and more), compare runs, etc

They are small startup that operates "under the radar". I got introduced to this product through the person who works there - and I really like the tool!!!

5. Performance Notes
The following issues and limitations are known to exist in this release of Performance Explorer
for Oracle. They are listed in several sub-sections (General, Operating System, Oracle
(General), Oracle 10g, Oracle 9.2, Oracle 8, and Windows 2000 disk performance issue).
General notes
• Negative value for SQL statistics displayed as a result of the Top SQL Search
The SQL Analysis Top SQL Search component of the Performance Explorer may display a negative
value on a SQL Top Search Statistic or on a displayed SQL ratio. This occurs when in a heavily used
database system the value of the SQL performance statistic counter is growing over 4x10^9 and
becoming negative. This affects all Oracle versions 8i, 9i, and 10g.
Operating System notes
• Failure to startup Performance Explorer after successful install.
Performance Explorer may fail to startup during the installation process if user choose not to install
provided JRE (Java Runtime Environment). It is strongly recommended to use JRE packaged with
Performance Explorer.
• Connection over SSH tunnels
When direct TNS connection from desktop to database is not allowed due to security reasons, you
can create SSH tunnel to connect to a database on a remote host. SSH Tunnel can be created using
"putty", "Secure CRT" or any other SSH software that support tunnel creation.
For example, to set up SSH tunnel for default database listener port 1521:
In Putty: select "SSH->Tunnels" Category, set "Source port to1521" and Destination to
"db_host:1521".
In “Secure CRT”: select "Session Options", "Advanced" , "Port Forwarding" tab, set "Local Port" to
1521, remote hostname to "db_host" and "Remote port" to 1521 as well.
After the SSH tunnel is setup, tnsnames.ora entry needs to be changed to have "127.0.0.1" or
"localhost" instead of name. For thin URL connections, please use "127.0.0.1" or "localhost" as well Oracle notes • Oracle JDCB Drivers. Sometimes due to minor differences between provided JDCB drivers and installed Oracle client connection to database cannot be successfully established. In this case it is recommended to copy the JDBC drivers from Oracle client installation to the “Performance Explorer\lib” and rename them to the proper classes12.jar name, i.e. classes129.jar is a proper name for Oracle 9i and classes1210.jar is a proper name for Oracle 10g Oracle notes (10g) • Use startup “Performance Explorer-i Statspack-AWR, 10g JDBC Driver” to use provided 10g JDBC drivers • Client for Oracle 10g Release 2: When you diagnose a 10g (Release 2) database, we recommended using a 10g (Release 2) Oracle client and/or 10g JDBC drivers. Earlier versions of the Oracle client have as yet unexplained issues with long-term connections to a 10g Release 2 server. Oracle notes (9.2) • Use startup “Performance Explorer-i Statspack-AWR, 9i JDBC Driver” to use provided 9i JDBC drivers Oracle notes (8i) • Use startup “Performance Explorer-i Statspack-AWR, 8i JDBC Driver” to use provided 8i JDBC drivers . . . . . . .. . . . . . . .. . . . . . . .. . . . . . . .. . . . . . . .. . . . . . 6.
