由于休眠状态，Tomcat慢启动

目前对我的应用程序使用Tomcat 6和hibernate 3，但我注意到启动速度很慢，我只映射了大约40个实体。不知道这是Hibernate导致日志如下：由于休眠状态，Tomcat慢启动

需要大约5分钟为以下：

任何想法？顺便说一句我已经尝试增加tomcat的内存

Hibernate的配置：

    <property name="dataSource"> <ref bean="dataSource" /> </property> 
    <property name="mappingJarLocations">

更新：我已经启用了更精细的记录，来到下方，它打印出下面的5分钟，任何想法？

是否为所有软件包（*）启用了调试日志记录？如果是的话，也许尝试重新运行跟踪记录的整个事情，也许它会揭示'SessionFactoryObjectFactory.addInstance（105）'和'GnrlLookupView之间的5-6分钟内发生了什么。（37）'。 –

您使用的是什么版本的Java？你分配了多少内存？你有多少物理内存？ – pczeus

使用java 1.6，这是我在启动时的配置：-server -Xms3072m -Xmx3072m -XX：NewSize = 1024m -XX：MaxNewSize = 1024m -XX：PermSize = 1024m -XX：MaxPermSize = 1024m -XX：+ DisableExplicitGC – mel3kings

发现答案不是由于休眠设置，似乎在启动时应用程序正在加载大量表并试图保存在缓存中。
