While profiling the users system found that the methods org.jbpm.job.executor.JobExecutorThread.getWaitPeriod(int) and org.jbpm.job.executor.JobExecutorThread.getNextDueDate() are taking 2.58 seconds to run.

This is true even though the client is not using JBPM and has nothing added to the database. It appears to be do to a lack of an index on the query.

Since they don't use JBPM in this implementation of ESB we are just taking it out.
