Huisheng I took the standard configuration for 4.3. Where can I decrease transaction isolation? Maciej: I added your configuration part to jbpm.hibernate.cfg.xml. The results are better, but 70 ms vs. 25 ms is not really good. jbpm.hibernate.cfg.xml <?xml version="1.0" encoding="utf-8"?> <!DOCTYPE hibernate-configuration PUBLIC           -//Hibernate/Hibernate Configuration DTD 3.0//EN           http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd> <hibernate-configuration>     <session-factory>         <property name="hibernate.dialect">org.hibernate.dialect.MySQLInnoDBDialect</property>         <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>         <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/jbpm</property>         <property name="hibernate.connection.username">username</property>         <property name="hibernate.connection.password">password</property>         <property name="hibernate.hbm2ddl.auto">create-drop</property>         <property name="hibernate.format_sql">true</property>         <property name="hibernate.use_sql_comments">true</property>         <property name="hibernate.cache.provider_class">org.hibernate.cache.HashtableCacheProvider</property>         <property name="hibernate.cache.provider_class">org.hibernate.cache.HashtableCacheProvider</property>         <property name="hibernate.cache.use_second_level_cache">true</property>         <property name="hibernate.cache.use_query_cache">true</property>         <mapping resource="jbpm.repository.hbm.xml" />         <mapping resource="jbpm.execution.hbm.xml" />         <mapping resource="jbpm.history.hbm.xml" />         <mapping resource="jbpm.task.hbm.xml" />         <mapping resource="jbpm.identity.hbm.xml" />         <class-cache usage="nonstrict-read-write"/>         <class-cache usage="nonstrict-read-write"/>         <class-cache usage="nonstrict-read-write"/>         <class-cache usage="nonstrict-read-write"/>         <class-cache usage="nonstrict-read-write"/>         <class-cache usage="nonstrict-read-write"/>         <class-cache usage="nonstrict-read-write"/>         <class-cache usage="nonstrict-read-write"/>         <class-cache usage="nonstrict-read-write"/>         <class-cache usage="nonstrict-read-write"/>         <class-cache usage="nonstrict-read-write"/>     </session-factory> </hibernate-configuration> Regards, Christian -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/536565#536565] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
