Run vmstat (or your preferred performance monitor) on the box (vmstat 1 might
be appropriate for you). Leave it idle. Watch vmstat as the box "wakes up"
Tomcat. What's happening - disk i/o? CPU? Paging traffic?
My first guess is that some other process has caused large chunks of Tomcat's
heap to be paged out, and the delay is due to paging issues. If you use a
back-end database, this could also happen to the database.
