I am using a replicated ehcache which is deployed in Tomcat 7 environment. What happens here is that tomcat takes too long to startup with the logs getting filled up with ehcache heartbeat messages.
Any thoughts as to how we can speedup ehcache and Tomcat startup?

You need to change bootstrapper strategy to be asynchronous (bootstrapAsynchronously=true
) to avoid delays during start up i.e.:
<bootstrapCacheLoaderFactory
class="net.sf.ehcache.distribution.RMIBootstrapCacheLoaderFactory"
properties="bootstrapAsynchronously=true, maximumChunkSizeBytes=5000000"
propertySeparator="," />
