Hey,
After learning some ANT basics i have managed to enhance my classes using
the ant script :-)
In each of my tests i have 10,000 iterations and at the end i calculate the
average execution time.
Insert/Update & Delete results are reasonable.. about 1.5x than plain JDBC.
But, Select (EntityManager.find()) performs pretty slow 2x and more than
plain JDBC.
Some details about my environment:
Client and Server are on different machines on my local network.
The properties i have in my persistence.xml file are:
<property name="ConnectionProperties"
value="DriverClassName=com.mysql.jdbc.Driver,
Url=jdbc:mysql://.......,
MaxActive=100,
MaxWait=10000,
Username=...,
Password=...,
TestOnBorrow=false,
poolPreparedStatements=true" />
<property name="jdbc.SynchronizeMappings"
value="buildSchema(ForeignKeys=true)"/>
<property name="ConnectionDriverName"
value="org.apache.commons.dbcp.BasicDataSource"/>
<property name="openjpa.Multithreaded" value="true" />
<property name="jdbc.DBDictionary" value="batchLimit=1000"/>
