speed up the init time of hibernate

[ola gerchikov]

I use hibernate in my webapp on tomcat.

I notice that it takes a lot time to setup my webapp (when i first hit my servlet). It takes about 4 seconds to start tomcat, but it takes 14 seconds to initialize my webapp.

Can you please tell me how can I speed up the init time of my web app?

Here is my hibernate.cfg.xml file, I think it is very simple.

   
<hibernate-configuration>
 
<session-factory>
 
<!-- Database connection settings -->
<property name="connection.driver_class">
com.mysql.jdbc.Driver
</property>


<property name="connection.url">
jdbc:mysql://localhost/nwebdb
</property>

<property name="connection.username">test</property>
<property name="connection.password">test</property>

 

 
<!-- SQL dialect -->
<property name="dialect">
org.hibernate.dialect.MySQLInnoDBDialect
</property>
 
<!-- Enable Hibernate's automatic session context management -->
<property name="current_session_context_class">thread</property>
 
<!-- Disable the second-level cache  -->

<property name="cache.provider_class">                                
org.hibernate.cache.EhCacheProvider
</property>

 

<property name="hibernate.cache.use_query_cache">true</property>


    <property name="hibernate.jdbc.use_streams_for_binary">true</property>
<!-- configuration pool via c3p0--> 
<property name="c3p0.acquire_increment">2</property> 
<property name="c3p0.idle_test_period">100</property> <!-- seconds --> 
<property name="c3p0.max_size">15</property> 
<property name="c3p0.min_size">3</property> 
<property name="c3p0.max_statements">0</property> 
<property name="c3p0.min_size">10</property> 
<property name="c3p0.timeout">100</property> <!-- seconds --> 

<mapping resource="com/test/A.hbm.xml" />
<mapping resource="com/test/B.hbm.xml" />
<mapping resource="com/test/C.hbm.xml" />
</session-factory>
 
</hibernate-configuration>
 
 

If you have any idea about how to speed up the init time of my web app, please let me know.
Thank you.

Creating a SessionFactory isn't that major an event. Are you sure the delay isn't Tomcat compiling a JSP or something?
