Tomcat slow startup due to hibernate

Question

Currently using Tomcat 6 and hibernate 3 for my application but I notice the startup is very slow,I only have about 40 entities mapped. Not sure if this is caused by hibernate the logs are below:

It takes around 5 mins for the below:

Any ideas? btw I have already tried increasing tomcat memory
